INDEPENDENT AUDITOR'S CONSENT



                          Independent Auditor's Report

To the Administrative Committee
Tower Automotive Products
   Savings Investment Plan
Novi, Michigan

We have audited the accompanying statement of net assets available for benefits
of the Tower Automotive Products Savings Investment Plan as of December 31, 2003
and 2002 and the related statement of changes in net assets available for
benefits for the year ended December 31, 2003. These financial statements are
the responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audits to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Tower
Automotive Products Savings Investment Plan as of December 31, 2003 and 2002 and
the changes in net assets available for benefits for the year ended December 31,
2003, in conformity with accounting principles generally accepted in the United
States of America.

Our audits were performed for the purpose of forming an opinion on the financial
statements taken as a whole. The supplemental schedule of assets held for
investment purposes is presented for the purpose of additional analysis and is
not a required part of the basic financial statements but is supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974. The supplemental schedule is the responsibility of the Plan's management.
The supplemental schedule has been subjected to the auditing procedures applied
in the audits of the basic financial statements and, in our opinion, is fairly
stated in all material respects in relation to the basic financial statements
taken as a whole.

TOWER AUTOMOTIVE PRODUCTS SAVINGS INVESTMENT PLAN

                                                   NOTES TO FINANCIAL STATEMENTS
                                                      DECEMBER 31, 2003 AND 2002

NOTE 1 - DESCRIPTION OF THE PLAN

            The following description of the Tower Automotive Products Savings
            Investment Plan (the "Plan") provides only general information.
            Participants should refer to the plan agreement for a more complete
            description of the Plan's provisions.

            GENERAL - The Plan is a defined contribution profit-sharing plan
            covering certain union employees of R.J. Tower Corporation (the
            "Company"), the Plan's sponsor. Eligible employees can become
            participants in the Plan upon completion of the probationary period
            specified in the collective bargaining agreement. The Plan is
            subject to the provisions of the Employee Retirement Income Security
            Act of 1974 (ERISA).

            CONTRIBUTIONS - Participants may elect to make contributions to the
            Plan through payroll deductions of 1 percent to 90 percent of the
            participant's compensation, as defined. The Plan also allows
            participants to transfer funds from other employer-qualified plans
            into the Plan.

            The Company may make a matching contribution based on the
            participant's contributions. This matching contribution amount is
            determined by a collective bargaining agreement with the covered
            union. Participants must generally be employed as of the last day of
            the plan year in order to share in Company-matching contributions. A
            participant whose employment terminated during the plan year after
            reaching age 65, because of death or disability, or as a direct
            result of job abolition or permanent reduction in personnel is also
            eligible to share in matching contributions.

            PLAN OPERATIONS - The Company appointed New York Life Trust Company
            to act as trustee of the Plan. The Company has also appointed a
            committee of employees of the Company to act as plan administrator.
            The trustee is responsible for holding the investment assets of the
            Plan, executing investment transactions and making distributions to
            participants. The plan administrator interprets and communicates the
            provisions of the Plan and ensures that all government and
            participant reporting requirements are fulfilled, and approves all
            distributions from the Plan to participants.

            PARTICIPANT ACCOUNTS - Individual accounts are maintained for each
            participant, with benefits limited to the amount contributed to the
            participant's account plus or minus any allocation of income,
            expenses, gains, or losses. Participants direct the investment of
            their accounts among various investment options offered by the Plan.
            Allocations to participant accounts are based on compensation or
            account balances, as specified by the plan agreement. The benefit to
            which a participant is entitled is the benefit that can be provided
            from the participant's vested account.

                                                   NOTES TO FINANCIAL STATEMENTS
                                                      DECEMBER 31, 2003 AND 2002

NOTE 1 - DESCRIPTION OF THE PLAN (CONTINUED)

            VESTING - Participants are immediately vested in their voluntary
            contributions plus actual earnings thereon. Vesting in the
            Company-matching contribution account is based on years of service
            as defined in the Plan, as follows:



                                           Vesting
 Years of Service                        Percentage
 ----------------                        ----------
                                      
Less than 2 years                             0
2 years                                      40
3 years                                      60
4 years                                      80
5 years                                     100


            LOANS TO PARTICIPANTS - Under certain conditions, a participant may
            obtain a loan from the Plan. A participant's loan cannot exceed the
            lesser of $50,000 or one-half of the participant's nonforfeitable
            interest in the Plan. The loan will bear a reasonable interest rate,
            be adequately secured, and not exceed a period of five years.
            Principal and interest is paid ratably through payroll deductions.

            PAYMENT OF BENEFITS - Upon termination of service, a participant may
            elect to receive either a lump-sum amount equal to the value of the
            participant's vested interest in his or her account, or periodic
            payments, at least annually, of equal amounts of at least $600 over
            a period not to exceed 15 years. In-service withdrawals are also
            allowed under the terms of the Plan under certain circumstances.

            FORFEITED ACCOUNTS - Forfeited balances of terminated participants'
            nonvested accounts may be used to reduce Company-matching
            contributions or pay the administrative expenses of the Plan for the
            plan year in which the forfeiture occurs or the next plan year.

NOTE 2 - SUMMARY OF ACCOUNTING POLICIES

            BASIS OF ACCOUNTING - The financial statements of the Plan are
            prepared using the accrual basis of accounting.

                                                   NOTES TO FINANCIAL STATEMENTS
                                                      DECEMBER 31, 2003 AND 2002

NOTE 2 - SUMMARY OF ACCOUNTING POLICIES (CONTINUED)

            ASSETS AND LIABILITIES - Accounting policies relative to the basis
            of recording assets and liabilities conform to Department of Labor
            guidelines. The fair value of the pooled separate account is based
            on the quoted market prices of the underlying assets. Investments in
            money market and mutual funds and shares of common stock are valued
            at market value as determined by quoted market prices. Participant
            loans are stated at face value, which approximates fair value.

            ADDITIONS, DEDUCTIONS, AND CHANGES IN NET ASSETS - Additions and
            deductions are recorded as earned and incurred. Since assets of the
            Plan are recorded at fair value, unrealized appreciation or
            depreciation of plan assets for the year is recorded in the
            statement of changes in net assets available for benefits.
            Contributions are recorded on the accrual basis in the plan year to
            which the contribution applies. Distributions to beneficiaries are
            recorded when distributed by the Plan. Administrative expenses are
            recorded when incurred.

            ADMINISTRATIVE EXPENSES - Certain administrative expenses and
            withdrawal fees charged by the Plan's trustee are paid out of plan
            assets. All other expenses incurred in conjunction with the Plan are
            paid by the Company.

            USE OF ESTIMATES - The preparation of financial statements in
            conformity with accounting principles generally accepted in the
            United States of America requires management to make estimates and
            assumptions that affect the reported amounts of assets and
            liabilities and disclosure of contingent assets and liabilities at
            the date of the financial statements and the reported amounts of
            additions and deductions during the reporting period. Actual results
            could differ from those estimates.

NOTE 4 - RELATED PARTY TRANSACTIONS

            Certain plan investments are shares of a pooled separate account,
            mutual funds, and a money market fund managed by New York Life Trust
            Company. New York Life Trust Company is the trustee, as defined by
            the Plan; therefore, these transactions qualify as party-in-interest
            transactions.

            Participants may elect to invest in Tower Automotive, Inc. common
            stock. Tower Automotive, Inc. is the parent of the sponsor of the
            Plan.

NOTE 5 - PLAN TERMINATION

            Although it has not expressed any intent to do so, the Company has
            the right under the Plan to discontinue its contributions at any
            time and to terminate the Plan subject to the provisions of ERISA.
            In the event of termination, participants will become 100 percent
            vested and amounts credited to participants' accounts will be
            distributed to participants in accordance with the Plan's
            provisions.

NOTE 6 - TAX STATUS

            The Plan obtained its latest determination letter dated November 6,
            2001, in which the Internal Revenue Service stated that the Plan, as
            then designed, was in compliance with the applicable requirements of
            the Internal Revenue Code. The Plan has been amended since receiving
            the determination letter. However, after consulting with legal
            counsel, the plan administrator believes that the Plan is currently
            designed and being operated in compliance with the applicable
            requirements of the Internal Revenue Code. Therefore, no provision
            for income taxes has been included in the Plan's financial
            statements.
