71 RT 340 (w/air) fan and clutch?

[ChallengerGreg]

I’m trying to figure out which fan and clutch unit would have been installed on a 71 Challenger RT 340 w/air. The car currently has a 20” five bladed fixed fan and a 26” radiator. Any help would be appreciated.

you need a 216 fan

And that is a unit that requires a clutch.
