Tail lights

Correct me if I am wrong but arent the tailights for the Conestoga and sedans different than the coupe for 54-55. I thought that the coupes were shorter and had more of a flat surface and used a flat tail light. The wagons were taller and had a more round housing and used a rounded/domed tail light. look at ebay items 4612938526 i think this a sedan wagon tail light and item 8038193696 is for the coupe speedster.Thanks Nick
