I just came across Summit Racing selling the '64 and '65 Chevelle Goodmark rear deck filler panel for only $99. It is the one that includes reinforcing panel attached below. It is part number 4030-710-641. Surely this is identical to fitting my '65 GS or any GM a-body of that year, right...? Or do Chevelles actually have a different style rear window-channel-to-trunk area? I swear this panel should fit...even if only for the lower rear window channel patch and the little hump for the package tray to slide under. Any help appreciated!
