Valiant Convertible

I have stumbled upon a 65 Valiant Convertible. Factory 273/904, white top and red interior. Not sure of original exterior color yet.

It's been in a barn for a number of years and at some point somebody attempted to put patch panels on the passenger side quarter panel and both floor boards. Also, at some point many of the chrome trim pieces were removed from the top assembly and windshield frame as well as the rear seat assembly and rear seat side panels.

Are 63 to 66 Dodge and Plymouth A bodies floor pans interchangeable. Do wagons, and 4 doors use same floors as well?
I have a complete trunck floor from a 65 B'Cuda I could use but want a complete passenger floor pan.

I'm trying to figure out what to do with car as it will need significant sheet metal work and miscellaneous trim items to bring it back to life.
