TO:
ALL CHEVROLET DEALERS
General Motors has determined that some 1985 Full Size Chevrolet models equipped with SEO 9C1 (Police Package) and (Special
Handling Suspension) SEO 7B3 may have been assembled with standard front and rear springs rather than the heavy duty springs
that were ordered. As a result, accelerated suspension deterioration can occur.
To correct this condition the front and rear springs will be inspected and when required, replaced on all involved vehicles.
Vehicles Involved
Involved are certain 1985 Full Size Chevrolet models equipped with SEO 9C1 (Police Package) and (Special Handling Suspension)

Involved vehicles have been identified by Vehicle Identification Number Computer Listings. Computer listings contain the

bulletin. Owner name and address data furnished will enable dealers to follow-up with owners involved in this campaign.
These listings may contain owner names and addresses obtained from State Motor Vehicle Registration Records. The use of such
motor vehicle registration data for any other purpose is a violation of law in several states. Accordingly, you are urged to limit the
use of this listing to the follow-up necessary to complete this campaign. Any dealer not receiving a computer listing with the
campaign bulletin was not shipped any involved vehicles.
