Wow I think that 4 blade is an antique 6cyl fan. check the pick that is on an all original 1950 216cui 6 that i got for my brothers car.

Definately use the clutch fan 3 blade, although most V8 fans ive seen were 5 blades, I'm sure you could probably locate one pretty easy and cheap. think i have one laying around i'd give you if you were closer.

I believe the firewall is specific to ac or non ac so you will need to use the appropriate one for the cab, the heater/ac boxes can be easily repaired with a little fiberglass work and spray paint. they're pretty hard to find in pristene condition. later
