Do 1970-72 skylarks/gs have right above the package tray 2 plastic end finish pieces and a plastic middle center section? Or is the middle center section painted metal only?
The lil plastic pieces in the corners have been dubbed "eggshells" because they are brittle and tend to crack. The middle section that they screw to is a piece of the metal package tray and is also metal. Jim
I found them online/ebay for 1968-72 GM A-body Chevelle, 70-72 Monte Carlo Rear Package Tray Window Trim Corners. By inline tube
These are NOT the corner pieces you are looking for... (Move along). I've gotten ALL of the usable ones from my local yard. I believe the parts you seek are either from TPP or CARS. http://oldbuickparts.com/ https://www.thepartsplaceinc.com/
If I did not have Black interior. I think I would be in trouble. But Black butal on glass saved it I think
