Check out a Hayden 2765 clutch fan. It is the shortest clutch fan, actually made for a Jaguar.
Its kind of the go to fan for these tight clearance situations. I have one on my 360 Dart.
Be ready for some finger gymnastics putting it on. Very tight. Google the part number for some info, many Mopar folks have gone this route.
Update: Hayden 2947 is the heavy duty version.
How long until someone comments on the chrome thermostat housing ?
