Hey, everyone! I've started my big disassembly on my '64 and I hit a little snag. The parking brake cable part of the pushbutton unit is held in place with a cotter pit and a crimped bit of metal as seen in this picture. Anyone have any experience taking these apart? I know the obvious solution is to force it open, but I don't want to damage anything if I don't have to. Any help would be greatly appreciated. Thanks!
