I have a few questions regarding the interior quarter trim panles for a 70 fastback. I am refering to the parts that have the small light attached to them. First, I tried replacing them with a reproduction cardboard panel. It seems as though the heat (I think) made the cardboard panel warp. They are no longer flat. Any ideas on how to prevent that from happening? Second, I believe the upper portion is pinched under the window W/S and the lower portion is held in by the trim panel......what happens along the area where it meets the headliner? I appreciate any help. Thank-you.
