Looking on Advice to fix the Piece of my ZR2 Blazer that sits between my back seat passenger windows and my rear quarter windows.
There is a massive hole and cracking in my passenger side plastic.

 

Are you asking about reparing one of the interior trim pieces?

If yes, you can likely get what you need from a wrecking yard.

However, I've haf some success repairing these pieces by welding them together with acetone. This works becsuse they are made of ABS plastic.

 

I am looking to repair the exterior pieces.
