Question on 1965 Dart GT Charger

Clroads,
You might be confusing most people here. What prompted your contemplations about "7 speed", "AWD", "single speed rear", and "guessing RWD"? None sounds relevant to any U.S. cars in the 1960's. Anyway, we would all be interested if you found any info about fiberglass floor panels (Plaza Fibreglass).
