Form 10-K for the fiscal year ended January 2, 2005

Item 2 - Properties, page 17

1. Reference is made to the second paragraph on page 18.  We note
you
disclose that in connection with disposition of the Livonia
Fittings
business to TriMas, you are subleasing the Livonia, Michigan
facility
to TriMas and remain responsible for payments to the lessor.  In
this
regard, tell us how you have considered FIN No. 45 as it appears
that
you remain secondarily liable for the lease payments.  Please
clarify
for us and in your notes to the financial statements how your
accounting treatment with respect to the sublease arrangement
complies with the guidance as outlined in paragraph 9 of FIN No.
45.
Tell us, if any, the amount representing the fair value of the
liability that you have recognized within your financial
statements
as a result of the obligation to stand ready to perform and how
fair
value was determined.  Also, please revise your notes to the
financial statements in future filings to include the disclosures
as
required by paragraph 13 of the FIN No. 45.  If you believe that
your
obligation under the sublease arrangement does not represent a
guarantee which should be accounted for under FIN No. 45, please
explain in detail the basis for this conclusion.

Item 7 - Management`s Discussion and Analysis, page 22
Contractual Cash Obligations, page 43

2. We note that your disclosure which indicates that you are
contingently liable for future products warranty claims and that
you
provide extensive warranties to your customers; however, it does
not
appear that you have provided the disclosures as required by
paragraph 14 of FIN No. 45.  In this regard, please revise future
filings to disclose your accounting policy and methodology used in
determining your liability for product warranties and provide a
reconciliation of the changes in your aggregate product warranty
liability for the year.

Quantitative and Qualitative Disclosures about Market Risk, page
48

3. Please revise your discussion regarding your exposure to
interest
rate risk and to include all of the disclosures required by Item
305(a) of Regulation S-K (e.g. sensitivity analysis).

Consolidated Statements of Cash Flows, page 53

4. We note that you recognized a loss on fixed assets of
approximately $15 million for the fiscal year ended December 28,
2003; however, it appears that little, if any, information
regarding
the loss on fixed assets has been provided in your notes or MD&A
section of your document.  In this regard, please tell us and
revise
the notes to your financial statements and MD&A in future filings,
where appropriate, to discuss in greater detail the facts and
circumstances surrounding the loss on fixed assets of $15 million
and
explain where the amount has been classified in the statements of
operations.  Also, if the loss recognized was not included as a
component of operating profit, revise future filings to reflect
such
losses as a component of operating profit.  Refer to the
requirements
of paragraphs 25 and 45 of SFAS No. 144.

Note 6 - Equity Investments and Receivables in Affiliates, page 60

5. Reference is made to the third paragraph on page 61.  We note
that
you disclose 924,000 shares of TriMas stock was sold to Masco
Corporation for $23 per share in November 2004.  Please tell us
and
revise future filings to disclose how the value of the TriMas
stock
at $23 per share was determined and why you believe it is
appropriate.  We may have further comment upon receipt of your
response.

Note 6 - Equity Investments and Receivables in Affiliates

6. In future filings, please revise the notes to your financial
statements to include all of the disclosures required by paragraph
20
of ABP 18 with respect to your various equity investments.  These
disclosures should include the name of each investee and the
percentage interest held as of each balance sheet date presented.

Note 11 - Long-term Debt, page 65

7. We note the disclosure in Note 11 indicating that as a result
of
the 2004 credit facility amendment, $1.2 million of the
unamortized
balance related to the 2003 credit facility amendment was expensed
in
2004.  Please tell us and clarify in Note 11 why $1.2 million of
the
unamortized debt issuance costs associated with the 2003 amendment
were expensed in 2004 and explain how you calculated or determined
the amount that was expensed as a result of the 2004 amendment.

Note 14 - Derivative Financial Instruments, page 69

8. Reference is made to the last paragraph of your footnote.  We
note
that your disclosure indicates that your interest rate protection
arrangements matured in February 2004 and as a result, you
recorded a
cumulative pre-tax non-cash gain of $6.6 million in your
statements
of operations for the fiscal year ended January 2, 2005.  However,
we
also note that prior to their maturity, $6.6 million, net of tax
was
included in accumulated other comprehensive income as shown on
your
statements of shareholders` equity.  In this regard, it is unclear
why the pre-tax and net of tax amounts relating to the interest
rate
protection arrangements are the same.  Please clarify and
reconcile
the amounts for us.

Note 15 - Segment Information, page 69

9. Since it appears that you allocate income taxes to your
segments,
please revise future filings to include a reconciliation of
Adjusted
EBITDA for your segments to the Company`s income or loss before
cumulative effect of a change in accounting principle.  Refer to
the
requirements of paragraph 32b of SFAS No.131.

Note 16 - Acquisitions, page 73

10. We note that you completed the transaction with
DaimlerChrysler
which transferred full ownership of the New Castle Machining and
Forge manufacturing operations to Metaldyne during the first
quarter
of fiscal 2004 and according to your disclosure, you exchange $215
million in consideration for DaimlerChrysler`s interest in the
joint
venture.  Further, we note the fair value of the net assets
acquired
in connection with DaimlerChrysler`s interest in New Castle
approximated $168 million.  In this regard, please clarify for us
and
explain in your notes to the financial statements the reason(s)
for
the difference between the purchase price amount of $215 million
and
the net assets acquired of $168 million.  Also, please explain why
the fair value of the 10% senior subordinated notes and the Series
A-
1 preferred stock had a fair value less than their states values
at
December 31, 2003.  If the securities were valued at less than
their
stated values, please explain why.  Additionally, for intangible
assets subject to amortization, please revise future filings to
disclose the weighted average amortization period, in total and by
major intangible asset class.

11. We note during fiscal 2003, you acquired a facility in
Greensboro, North Carolina from Dana Corporation and in connection
with the acquisition you also signed a seven year supply agreement
with Dana covering all existing businesses at Greensboro.  Please
clarify for us whether this agreement was terminated in September
2004 as discussed on page 79 of your Form 10-K for the fiscal year
ended December 28, 2003 as it is unclear based on the notes to
your
consolidated financial statements for the fiscal year ended
January
2, 2005.  If the agreement was terminated, tell us and revise
future
filings to discuss, where appropriate, the effect the terminated
agreement had on the Company`s financial statements and future
results of operations to the extent the material.  Also, tell us
and
clarify in the notes to your financial statements whether any
portion
of the purchase price for the Greensboro facility was allocated to
the supply arrangement with Dana.  If not, please explain why.

12. Please explain in further detail why "unamortized accretion"
relative to the 10% senior subordinated notes resulted in
recognition
of $33.6 million of goodwill for tax purposes versus the $28.8
million of goodwill recognized for book purposes.  As part of your
response, please explain why there was unamortized accretion
associated with the notes issued.

Note 20 - Supplementary Cash Flow Information, page 77

13. Please tell us and clarify in the notes to your financial
statements in future filings, why asset impairment losses
associated
with your Bedford Heights, Ohio and Rome, Georgia manufacturing
facilities were recognized during both 2003 and 2004.  Your
response
and your revised disclosures should explain how both the $4.9
million
asset impairment charge recognized during 2003 and the $7.6
million
charge recognized in 2004 were calculated or determined.  Your
response should also explain why the $4.9 million charge
recognized
during 2003 was not recognized until the fourth quarter of that
fiscal period.

Note 23 -  Income Taxes, page 80

14. The amount of deferred and refundable income taxes at December
31, 2004 of $18,470 as reflected in your consolidated balance
sheet
does not agree to the amount disclosed in Note 23 of $12,920.  In
future filings, please reconcile and revise these disclosures.

Note 26 - Interim and Other Supplemental Financial Data
(Unaudited),
page 87

15. Please explain why the $15 million fixed asset disposal loss
and
the $20.7 million of equity in losses of affiliates were not
recognized until the fourth quarter of fiscal 2003.

Schedule II - Valuation and Qualifying Accounts, page 108

16. Please revise future filings to include inventory valuation
and
other qualifying valuation account(s) using the format prescribed
in
Rule 12-09 of Regulation S-X for each of the periods presented in
your financial statements.  Refer to Rule 5-04 of Regulation S-X.
