Re: Door Change(s) Between '90 and '91 ?
One minor change in door trim happened somewhere in early 91 production.The trim on the early 91s has 7 threaded 10MM studs that bolt it to the door while a production change had the trim with a 1 stud at each end and clip retainers in the middle of the door.To get the the early trim off the door the door has to come completely apart.I dont know why G.M. would design the early 91 trim to be bolted on when the trim for the 90s was of the later design with the snap clips.I believe this bolt on trim was the only design on a C4,lucky me.
