         RE:      MCCLAIN INDUSTRIES, INC. REGISTRATION STATEMENT ON FORM S-8
                  1999 RETAINER STOCK PLAN FOR NON-EMPLOYEE DIRECTORS

Gentlemen:

         We have acted as counsel to McClain Industries, Inc. (the "Company"), a
Michigan corporation, in connection with the registration by the Company of up
to 100,000 shares (the "Shares") of Common Stock, no par value, to be issued and
sold by the Company from time to time pursuant to the McClain Industries, Inc.
1999 Retainer Stock Plan for Non-Employee Directors, as described in the
Registration Statement on Form S-8 to be filed with the Securities and Exchange
Commission (together with all amendments thereto, the "Registration Statement").
As your counsel in connection with this transaction, we have examined the
proceedings taken and are familiar with the proceedings proposed to be taken by
the Company in connection with the sale and issuance of the Shares.

         We do not purport to be experts on or to express any opinion in this
letter concerning any law other than the laws of the State of Michigan, and this
opinion is qualified accordingly. This opinion is limited to matters expressly
set forth in this letter, and no opinion is to be inferred or may be implied
beyond the matters expressly so stated. In rendering the opinion contained in
this letter, we have assumed without investigation that the information supplied
to us by the Company is accurate and complete.

         Based upon and subject to the foregoing, it is our opinion that the
Shares have been duly authorized, and upon the issuance and sale thereof in the
manner referred to in the Registration Statement, will be validly issued, fully
paid and non-assessable.

            We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and further consent to the use of our name wherever it
appears in the Registration Statement.

                                                 Very truly yours,

                                            JAFFE, RAITT, HEUER & WEISS
