ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

RESULTS OF OPERATIONS
The following table sets forth, for the periods indicated, Aetna's and MS
Acquisition's statement of operations expressed as a percentage of net sales.
This table and subsequent discussions should be read in conjunction with the
condensed consolidated financial statements and related notes thereto of Aetna
and MS Acquisition included elsewhere herein.  MS Acquisition was formed
primarily for the purpose of purchasing Aetna, and it does not have any
significant assets or liabilities, other than preferred stock, junior
subordinated debentures and accruals.  Additionally, MS Acquisition does not
have any incremental net sales or significant expenses, other than the interest
expense associated with the junior subordinated debentures and the related
income tax benefit.

NET SALES:  Net sales for Aetna and MS Acquisition for the third quarter of
1997 were $45.6 million, or 6.7% lower than third quarter 1996 sales of $48.9
million. Production sales of $44.5 million in the third quarter of 1997 were up
$0.1 million from $44.4 million in the third quarter of 1996, while tooling and
prototype sales were down $3.4 million for the same period of the prior year.
Production sales were favorably impacted by several new Chrysler car models and
increased Chrysler mini-van sales, partially offset by decreased Chrysler Jeep
Cherokee (XJ) sales.  Tooling sales in the third quarter of 1996 included
Chrysler Jeep Grand Cherokee (WJ) platform work.

GROSS PROFIT:  Aetna's and MS Acquisition's gross profit was $4.6 million, or
10.0% of net sales, for the third quarter of 1997, compared to $6.0 million, or
12.2% of net sales, for the same period in 1996.  The decrease in gross profit
from the prior year was due to purchasing rather than manufacturing certain
parts.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS (CONTINUED)

SELLING, GENERAL AND ADMINISTRATIVE ("SG&A") EXPENSES:  SG&A expenses for Aetna
and MS Acquisition for the third quarter of 1997 were $4.7 million, or 10.2% of
net sales compared to $4.1 million, or 8.3% of net sales, for the same period
in 1996.  The increase, as a percentage of sales, was due to non-recurring
merger and acquisition expenses and additional engineering and quality
assurance staff in support of new platforms.

INTEREST EXPENSE:  Aetna's interest expense for the third quarter of 1997 was
$2.7 million, or 6.0% of net sales, compared to $2.3 million or 4.6% of net
sales in the same period in the prior year.  Interest expense was impacted by
higher levels of debt outstanding.  MS Acquisition also had additional interest
expense of $0.2 million, or 0.4% of sales, which is attributed to the junior
subordinated debentures.

INCOME TAXES:  The income tax credit for Aetna in the third quarter of 1997 was
$1.1 million with an effective tax rate of 40.0% as compared to a credit of
$0.3 million with an effective tax rate of 100% in the same period in the prior
year.  The income tax credit for MS Acquisition in the third quarter of 1997
was $1.2 million with an effective tax rate of 40.0% as compared to a credit of
$0.4 million with an effective tax rate of 82.7% in the same period in the
prior year.  The effective rates in both periods and for both Aetna and MS
Acquisition differed from the statutory rate due principally to the effect of
non-deductible amortization of cost in excess of net assets acquired.

EXTRAORDINARY ITEM:  During the quarter ended September 29, 1996, Aetna and MS
Acquisition prepaid outstanding subordinated debt.  The resulting prepayment 
penalty has been shown as an extraordinary item.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS (CONTINUED)

NET SALES:  Net sales for Aetna and MS Acquisition for the nine months ended
September 28, 1997 were $149.4 million, down from the $163.8 million
reported   for the nine months ended September 29, 1996. Production sales
decreased $8.4 million, while tooling sales decreased $6.0 million.  The
decrease in production sales was principally due to the five week Chrysler
strike and the planned phase out of two General Motors programs (the cargo van
floor pan and side rail assemblies and the small truck door beam program)
during the second quarter of 1996.

GROSS PROFIT:  Aetna's and MS Acquisition's gross profit was $18.7 million, or
12.5% of net sales, for the nine months ended September 28, 1997 compared to
$22.4 million, or 13.7% of net sales, for the same period in 1996.  The
decrease in gross profit from the prior year was due to the lower sales volumes
and purchasing rather than manufacturing certain parts.

SELLING, GENERAL AND ADMINISTRATIVE ("SG&A") EXPENSES:  SG&A expenses for Aetna
and MS Acquisition for the nine months ended September 28, 1997 were $12.5
million, or 8.3% and 8.4% of net sales, respectively, compared to $11.4
million, or 7.0% of net sales, for the same period in 1996.  As a percentage of
sales, the increase was due to the interruption of production sales during the
Chrysler strike and additional engineering and quality assurance staff in
support of new platforms.

INTEREST EXPENSE:  Aetna's interest expense for the nine months ended September
28, 1997 was $8.0 million, or 5.4% of net sales, compared to $6.4 million or
3.9% of net sales in the same period in the prior year.  Interest expense was
impacted by higher levels of debt outstanding.  MS Acquisition also had
additional interest expense of $0.7 million of interest expense, or 0.4% of
sales, which is attributed to the junior subordinated debentures.

INCOME TAXES:  The income tax credit for Aetna for the nine months ended
September 28, 1997 was $0.7 million with an effective tax rate of 40.0% as
compared to a provision of $1.8 million with an effective tax rate of 39.3% in
the same period in the prior year.  The income tax credit for MS Acquisition
for the nine months ended September 29, 1997 was $1.0 million with an effective
tax rate of 40.0% as compared to a provision of $1.8 million with an effective
tax rate of 39.4% in the same period in the prior year.  The effective rates in
both periods and for both Aetna and MS Acquisition differed from the statutory
rate due principally to the effect of non-deductible amortization of cost in
excess of net assets acquired.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS (CONTINUED)

LIQUIDITY AND CAPITAL RESOURCES

Aetna's and MS Acquisition's principal capital requirements are to fund working
capital needs, to meet required debt payments and to complete planned
maintenance and expansion expenditures.  At September 28, 1997 there was $25.3
million available under the Senior Revolving Credit Facility.  Management
currently anticipates that its operating cash flow, together with available
borrowings under the Senior Revolving Credit Facility, will be sufficient to
meet working capital requirements, capital expenditure requirements, and
interest requirements on debt obligations in the near term.  During 1998, the 
Company anticipates securing a separate credit line to support Saturn tooling
expenditure requirements.

Net cash flow used for operations for the nine months ended September 28, 1997
aggregated $2.8 million and $1.4 million for Aetna and MS Acquisition,
respectively.  This compares to net cash provided by operations of $4.3 million
for both Aetna and MS Acquisition in the same period in the prior year. The
decrease at Aetna and MS Acquisition was attributable to a decrease in net
income.  The decrease was partially offset by an increase in accounts
receivable due to a progress billing made on the new Jeep Grand Cherokee (WJ)
weld assembly program and an increase in accounts payable due to the
construction of Plant 10 which will be used in the production of the WJ.  Net
cash used for operations at MS Acquisition is also offset by an increase in
intercompany balances aggregating $1.9 million.

Net cash flow used for investing activities aggregated $9.1 million for
the nine months ended September 28, 1997 as compared to $3.2 million for the
same period in the prior year at both Aetna and MS Acquisition and consists 
principally of capital expenditures. The major capital projects during 1997 
have been the construction of Plant 10 and the renovation of Plant 7.  As part
of its growth strategy, the Company continues to seek and review acquisition 
candidates.

Net cash flows provided by financing aggregated $8.1 million and represented
increases in the Senior Revolving Credit Facility for Aetna and MS Acquisition.
In addition, MS Acquisition paid $1.4 million of its junior subordinated
debentures during the nine months ended September 28, 1997.   Net cash used for
financing in the same period in 1996 totaled $1.5 million and represented
principally the repayment of long-term debt and dividends, partially offset by
the proceeds of the issuance of Senior Notes.

To the extent dividends to Aetna Holdings, Inc. (Aetna Holdings)  to fund the
interest payments on the Junior Subordinated Debentures and interest payments
on the unfunded contractual obligations to former option holders are permitted
under the 11-7/8% Senior Note Indenture and the Senior Revolving Credit
Facility, interest on the Junior Subordinated Debentures and the contractual
obligations will be funded by cash dividends by Aetna to Aetna Holdings.
Additionally, up to $2.5 million in the aggregate principal amount of the
Junior Subordinated Debentures will be required to be redeemed by Aetna
Holdings from time to time to the extent dividends to Aetna Holdings are
permitted to be paid by the 11-7/8% Senior Note Indenture and the Senior
Revolving Credit Facility.  In February, May and August 1997, Aetna paid $1.5
million, $0.6 million and $0.2 million, respectively, representing interest and
prepayment of principal on these debentures and obligations on behalf of Aetna
Holdings.
