63 dart 270 convertible taillight

Hi folks, I am looking for a right taillight for my 63 dart 270 convertible. I have found one on ebay that looks just like the one I need but it may not be the correct one as it may be for the station wagon.

Does anyone know if there is somewhere to find out if the wagon and convertible 270 lens are interchangeable and is there some way to find out what parts are interchangeable between same year cars and models or different year models?

I have swapped both the left taillight and housing left and right and both fit so there doesnt appear to be any polarity issues I can see.

Thanks for all the super experience on the site, you guys are awesome with you help and knowledge.

John
