I was inside the trunk installing a second rear speaker and, in an act of momentary idiotness, I had forgotten I had already reinstalled the rear package tray after re-coloring it. Pushed up on the perferated insert that covers the missing speaker hole and instantly blew apart one of the slotted areas in the rear tray.
I glued back the various puzzle pieces to have it somewhat acceptable, but could really use a new shelf. There is an eBay seller with repro shelves, but they are for sedans.
Any line on hardtop parts/ parts cars, please add a post.
