SO my passenger side rear 1/4 panel is allllll messsed up. It can be beaten and filled to fix...well... i think & hope anyway, lol. Haven't been able to find anything online for replacement panel piece for it. It's a 1966 Buick Skylark the salvage/junk yards in my area do not have any of my car 1. Is there such a piece anywhere ? 2. If not does anyone have one they are up to sell ? 3. Are there any other models or years that will fit mine ?
