I have those little funky tail lights. I have noticed that there are two socket holders for the inside. One is straight and used the small bulbs. The other is zig zagged so the stop light bulb can be larger. This may fit the bill. I just have not figured out how to put the sockets in the zig zag holder since they are sold separate and without the bulb socket. The zig zag holder is sold through Chevy Parts of America. Maybe just a simple phone call?
TIA
