Article No. 89-23-1
FORD: 1988 TEMPO
LINCOLN-MERCURY: 1988 TOPAZ
ISSUE: Some late 1988 and all 1989 design passive restraint shoulder strap track assemblies must be modified in the "A" and "B" pillar areas in order to be used as service assemblies on units built before 5/03/88. This is necessary because of late 1988 model year production tooling changes to the "A" and "B" pillar limit switch mounting brackets on the track assemblies.
ACTION: Use the following procedure to service the passive restraint shoulder strap assemblies. Refer to the Master Car Parts Catalog to obtain the appropriate service replacement front seat shoulder strap track assembly part number.
