Just picked up some interior parts for a 69 Standard coupe interior coupe in black. I was buying the parts for the door panels. I can sell the sail panels and qtr inside panels right away. Everything is in really good shape, one sailpanel had a rip on the upper corner about 1.5 in, but I contact cemented it and you can hardly notice, the other one is perfect, just some dirt and a little warp. The qtr panels have no rips, just some warping and edge curl. So what are original GM coupe qtrs and sail panels in black worth?
