INDEPENDENT AUDITOR'S CONSENT






                          Independent Auditor's Report

To the Administrative Committee
Tower Automotive Union 401(k) Plan
Novi, Michigan

We have audited the accompanying statement of net assets available for benefits
of the Tower Automotive Union 401(k) 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 Union 401(k) 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 basic
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.

                                                   NOTES TO FINANCIAL STATEMENTS
                                                      DECEMBER 31, 2003 AND 2002

NOTE 1 - DESCRIPTION OF THE PLAN

            The following description of the Tower Automotive Union 401(k) 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 plan under Section
            401(k) of the Internal Revenue Code that covers certain union
            employees of R.J. Tower Corporation and subsidiaries (the
            "Company"), the Plan's sponsor. Eligible employees can become
            participants on the first day of the month or quarter, as
            applicable, following the date on which the Plan's eligibility
            requirements are met. 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 in the Plan and as limited by
            the participant's related union agreement. The Plan also allows
            participants to transfer funds from other qualified plans into the
            Plan. During the plan year ended December 31, 2003, $48,177 was
            transferred from the Plan into other Company qualified plans.

            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
            unions. The Company may also make a profit-sharing contribution as
            determined in accordance with the collective bargaining agreements.

            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, ensures that all government and participant
            reporting requirements are fulfilled, and approves all distributions
            from the Plan to participants.

NOTE 1 - DESCRIPTION OF THE PLAN (CONTINUED)

            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.

            VESTING - Participants are immediately vested in their voluntary
            contributions plus actual earnings thereon. Vesting in the employer
            contribution accounts is based on years of continuous service, as
            follows:

            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,

            permitted by collective bargaining agreement). 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
            installments, as determined by the collective bargaining unit.
            In-service withdrawals are also allowed under the terms of the Plan
            under certain circumstances.

            FORFEITED ACCOUNTS - Forfeited balances of terminated participants'
            nonvested accounts are first used to reduce Company contributions
            with any remaining forfeitures being used to pay administrative
            expenses.

            AMENDMENTS - The Plan was amended effective October 6, 2002 to
            reflect a new collective bargaining agreement between the Company
            and its Corydon, Indiana union colleagues.

                                                      DECEMBER 31, 2003 AND 2002

NOTE 2 - SUMMARY OF ACCOUNTING POLICIES

            BASIS OF ACCOUNTING - The accompanying financial statements of the
            Plan have been prepared on the accrual basis of accounting.

            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 accounts 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 company 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 March 22,
            2002, 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 consultation 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.
