No room!

You probably do have room for a clutch fan…if you pick the right clutch fan. The Hayden space-saver clutch is a half/baby step in the right direction; you can do much better with a '70s Mercedes clutch fan. See here and here.

this the set up? 72 Mercedes 350SL 4.5L 107 RADIATOR COOLING FAN 8 BLADE 16" & CLUTCH 1162051306

anywhere to get those fans at a reasonable price? is there a part number or anything to look up?
