do you have a pic of the tail end, just for reference?
Heres some ideas off the top of my head, could work for any car if you have the patience....
-Ford shoebox tail lights turned 90degrees
-Nash Ambassador tail lights(filler neck in driver side lamp)
-Oldsmobile 88 lights
-'58-ish corvette tail lights(actually graft into the top of your rear fender)
-anything studebaker
-early 50s caddy lights(not the boobie cones)
