i just bought a 1966 plymouth belvedere/satellite it has a 318 wide block and a automatic tranny now it has a satellite interior (i was told) with bucket seats and a console when i got in i noticed the bucket seats were loose and would tilt outwards i just thought maybe the mounts werent bolted in on that one side then i looked at the console it was for an automatic but this car had it on the column so it wasnt stock console. i took out the seats and noticed they only had one mount each and therefore must have had a bench seat i have looked around the net a little and havent found much some said they came standard with benches others said buckets someone please educate me on what my interior had when rolled off the line 

hey I have a 65 plymouth satilite its got the 383 with auto 727

but its got buckets with the console on the floor. the belvedere

had a bench seat and shifter on the column from factory in that model

so yours might be converted or was ordered that way new.
