My Camaro has the original dash as well. It is like Bruce's. It has a fiberboard back (pretty sure its not fiberglass) and dense closed cell foam pad. I can't tell if there is a thin plastic film on the pad, but I don't think so. I think the dye was shot right onto the padding. The molding process made the padding on the outside denser than the padding on the inside. That's why it looks like ther is a thin plastic film. I have a couple of high wear areas on my dash, so I'm pretty certain about the lack of a plastic film.
when i bought my 69 camaro, the dash was really messed up. it looked like it got melted in the sun and it had broke off from the dash. so when i went to remove it, i just cut it out of the car because of its poor condition. and it too had a thick plastic coating on the underside.
