I don't recall a thread about those, but it's fairly straight forward.

All of the nose sheet metal pieces interchange on all of the passenger cars. Rear fenders are different for the coupe/roadster compared to sedans. What's interesting about the roadster is it's door length is the same as a 5 window coupe. Say for instance a roadster was found where the body shell was pretty wasted. It's possible (and has probably been done more than once) to take the body shell components that are unique to the roadster (cowl top and windshield mounts underneath it, dash, doors, and tulip panel with top attachment pieces, and the B pillar braces) and graft them to the 5 window shell and have a Ford sheetmetal roadster. There are some other minor things but those are the biggies.
