Gentlemen:

This opinion relates to the registration statement on Form S-4 (the
"Registration Statement") being filed today by Newcor, Inc., a Delaware
corporation (the "Issuer"), and certain of its subsidiaries which are
"Subsidiary Guarantors" (as defined in the Registration Statement) with the
Securities and Exchange Commission (the "Commission") for the purpose of
registering under the Securities Act of 1933, as amended (the "Act"): (a)
$125,000,000 principal amount of the Issuer's 9 7/8% Series B Senior
Subordinated Notes due 2008 (the "Exchange Notes"); and (b) the Subsidiary
Guarantors' guarantees of the Exchange Notes (the "Subsidiary Guarantees"). The
Exchange Notes are to be issued in exchange for the Issuer's outstanding 9 7/8%
Senior  Subordinated Notes due 2008 (the "Notes") pursuant to the Exchange
Offer described in the Registration Statement. As your counsel, we have
examined such certificates, instruments, and documents and reviewed such
questions of law as we have considered necessary or appropriate for the
purposes of this opinion, and, on the basis of such examination and review, we
advise you that, in our opinion:

1.    The Exchange Notes have been duly authorized by all necessary corporate
      action on the part of the Issuer, and the Subsidiary Guarantees have been
      duly authorized by all necessary corporate action on the part of the
      Subsidiary Guarantors.

2.    When the Registration Statement has become effective and the Exchange
      Notes have been issued in exchange for the Notes pursuant to the Exchange
      Offer, the Exchange Notes will be legally issued and will be binding
      obligations of the Issuer, and the Subsidiary Guarantees will be

      legally issued and will be binding obligations of the Subsidiary
      Guarantors.

We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to us under the caption "Legal
Matters" in the prospectus forming a part of the Registration Statement. In
giving this consent, we do not thereby admit that we are within the category of
persons whose consent is required under Section 7 of the Act or the rules and
regulations of the Commission.

Very truly yours,



Miller, Canfield, Paddock and Stone, P.L.C.
