Metaldyne Corporation
47659 Halyard Drive
Plymouth, Michigan  48170

Dear Ladies and Gentlemen:

                  We have examined a copy of the Registration Statement on Form
S-4 (No. 333-99569), as amended (the "Registration Statement"), filed by
Metaldyne Corporation (the "Company"), with the Securities and Exchange
Commission (the "Commission") and relating to the registration pursuant to the
provisions of the Securities Act of 1933, as amended (the "Act"), of up to
$250,000,000 principal amount of 11% Senior Subordinated Notes due 2012 (the
"Exchange Notes"). The Exchange Notes, which upon the effectiveness of the
Registration Statement will be registered under the Act, will be issued in
exchange for a like principal amount of the Company's outstanding 11% Senior
Notes due 2012 (the "Original Notes"), which are not registered under the Act.
The Exchange Notes have been authorized pursuant to resolutions adopted by the
Board of Directors of the Company, and are identical in all material respects to
the Original Notes, except for certain transfer restrictions relating to the
Original Notes. The Exchange Notes will be issued pursuant to the Indenture (the
"Indenture") dated as of June 20, 2002, between the Company and the Bank of New
York, as trustee. In rendering this opinion, we have reviewed such documents and
made such investigations as we have deemed appropriate.

                  In our examination of documents, instruments and other papers,
we have assumed the genuineness of all signatures on original and certified
documents and the conformity to original and certified documents of all copies
submitted to us as conformed, photostatic or




                                      -2-


other copies. As to matters of fact, we have relied upon representations of
officers of the Company.

                  Based on the foregoing, and subject to the qualifications
stated herein, we are of the opinion that:

                  The Exchange Notes have been duly authorized for issuance and,
when duly executed, authenticated, registered, issued and delivered in exchange
for Original Notes of a like principal amount, in accordance with the terms of
the Indenture and as contemplated by the Registration Statement, will constitute
valid and binding obligations of the Company, enforceable against the Company in
accordance with their terms and entitled to the benefits of the Indenture,
subject to applicable bankruptcy, insolvency, reorganization, moratorium,
fraudulent conveyance and similar laws affecting creditors' rights and remedies
generally and subject to general principles of equity, including principles of
commercial reasonableness, good faith and fair dealing (regardless of whether
enforcement is sought in a proceeding at law or in equity).

                  We are members of the bar of the State of New York and do not
purport to be experts in, or to express any opinion concerning, the laws of any
jurisdiction other than the law of the State of New York, the Delaware General
Corporation Law and the federal laws of the Unites States of America.

                  Neither this opinion nor any part hereof may be delivered to,
used or relied upon by any person other than you without our prior written
consent.

                  We hereby consent to the filing of this opinion with the
Commission as an exhibit to the Registration Statement and to the reference of
our firm under the caption "Legal Matters" in the Registration Statement and
related prospectus. Our consent to such reference does not constitute a consent
under Section 7 of the Securities Act, and in consenting to such reference we
have not certified any part of the Registration Statement and do not otherwise
come within the categories of persons whose consent is required under said
Section 7 or under the rules and regulations of the Commission thereunder.

                                                  Very truly yours,



                                                  /s/ Cahill Gordon & Reindel
