Very common problem with original dash pads on any Camaro from 69-78. The type of molding process they used was not a very good one for long term use, say after 6 or 7 years, much less 40. It can be repaired, but it will be a temporary fix at best. I have used an industrial contact adhesive to fix original pads before. You need to heat the affected area enough to make it soft, but not too much to loosen anymore of it from the fiberglass backing that it is molded to. Apply a small amount of contact adhesive in the area that needs to be reattached. Now stretch the vinyl portion over the edge of the fiberglass backing, and clamp it down using some spring clamps and paint paddles to distribute the pressure evenly w/o leaving any high/low spots. (See picture for a spring clamp) Let it set at least 24hrs before trying to reinstall the dash pad so to make sure you have a good bond. There is no guarantee that it will not lift and peel as before once the car gets in the hot sun. I hope this helps...........RatPack.........................
