I added fold down seats to my 1970 Mach 1 about 10 years ago. A few days ago, I noticed that the fold down seat knocked a hole in the lower fiberglass panel where the rubber bumper on the seat meets the fiberglass panel - at about where a rear passenger migh rest his arm. Did the cars that came stock with fold down seats have any feature to reinforce/protect the fiberglass armrest area? Besides being gentle when the folding down the seat, what can I do to protect that quarter piece and keep it looking stock (its an original piece)? I will try to repair it but even repos are fairly pricy.
