Dealer Letter #125

SUBJECT: Help Us Speed up Service To You

Here's a way to help us get your check or credit voucher to you quicker for parts that were used in warranty repairs on Johnson stern-drive engines. Simply include the Johnson parts on one claim form - and the Chevrolet or Buick parts (with invoice from G. M. dealer) on another; then send both claims to us.

For those who are unfamiliar with the method used in our parts catalogs to distinguish between Johnson and Chevrolet or Buick items, see figure 1.

The part numbers printed on a grey background will always be Chevrolet or Buick parts, and must be purchased from your Buick or Chevrolet dealer.

The part numbers which appear in the white background will always be Johnson parts, and are available from your Johnson Parts Distributor.
