   Item 7.  Financial Statements and Exhibits

          (b)  Pro Forma Financial Information


                    UNAUDITED PRO FORMA FINANCIAL STATEMENTS


   The following unaudited Pro Forma Condensed Consolidated Balance Sheet as
   of March 31, 1997, gives effect to the sale on April 18, 1997, of the
   Company's automotive products business.  The Company classified its
   automotive products business as "Discontinued Operations" in its 1996 Form
   10-K.  As part of the Company's overall plan to sell its automotive
   products business, the Company also intends to sell its interest in its
   40% owned Mexican affiliate.  The sale of its Mexican affiliate has not
   been finalized, and accordingly, the Company's interest in the affiliate
   is shown as a net asset of discontinued operations.

   The Company received gross proceeds from the sale of automotive products
   of $727 million, which amount reflects additional investment and working
   capital changes from the initial price of $625 million and is subject to
   final adjustment.

   The Pro Forma Condensed Consolidated Balance Sheet reflects the proceeds
   received on April 18, 1997.  As of June 30, 1997, the Company used
   approximately $376 million to pay debt and $100 million to repurchase
   stock.  The remaining proceeds will be used to repurchase additional stock
   and make acquisitions.

   No Pro Forma Condensed Consolidated Statement of Earnings is presented
   because the Consolidated Statement of Earnings included in the Company's
   1996 Form 10-K and Form 10-Q for the quarter ended March 31, 1997,
   reflected the automotive products business as a discontinued operation. 
   Certain expenses have been allocated to the discontinued operations,
   including interest expense, which was allocated based on the ratio of net
   assets discontinued to the total consolidated net assets of the Company. 
   There are no pro forma adjustments which would have a material effect on
   income from continuing operations.  Pro forma earnings per share from
   continuing operations for the quarter ended March 31, 1997, would be $.40
   per share after considering the effect of the stock repurchase and
   assuming the purchases had occurred on January 1, 1997.

             NOTES TO PRO FORMA CONDENSED CONSOLIDATED BALANCE SHEET



    (A)  The company classified its Automotive Products Company as
         discontinued operations in 1996 (See "Discontinued
         Operations" note in the company's 1996 Form 10-K and notes to
         condensed consolidated financial statements in the company's
         March 31, 1997 Form 10-Q). The historical balance sheet
         reflects as short term debt the amount of debt that was
         repaid with a portion of the sales proceeds received from the
         sale of the automotive business.

    (B)  The disposition adjustments reflect the cash proceeds from
         the sale of the automotive business, the elimination of the
         net current and long - term assets of the automotive business
         other than assets and liabilities retained, repayment of
         short-term debt, stock repurchases, the estimated after-tax
         gain on sale of the business, and the associated tax
         liability.

    (C)  The actual gain to be recorded as of April 18, 1997 may
         differ from the estimated gain reflected in the March 31,
         1997 pro forma balance sheet. The Company and the buyer  are
         in the process of negotiating the final amounts of certain
         items.
