This bulletin supplements Dealer Technical Bulletin 86-T-9A dated October 15, 1986.
Late production 1986 door glass regulator assembly on two-door models with power windows included an up stop. This expanded to all power front
door glass regulators after October 1, 1986, on the 1987 Delta 88 and Ninety-Eight models.
The added up stop prevents tape drive over-travel and disengagement of the tape drive from the door glass. If a car has this condition and does not have
an up stop, replace it with the later design. Part numbers and usage are indicated in the following chart:
