: 71 350 A/C clutch fan clutch

Mar 1st, 06, 3:44 PM
I have a couple clutch fans off of 71 small block A/C cars.
Both are #3989095 7 blade fans.
I need to get a replacement clutch for one of them.
The clutch has an "S" on the front (Schaefer?)
I have not been able to find one that fits the fan.
Mine have a rectangular bolt pattern where the clutch bolts to the fan blade assy. The pattern is 2 1/8" x 3 5/8 ".
Everything I have found is a square bolt pattern.
Anyone have info on where to get one that is correct.
I am not interested in aftermarket fan assemblies, a good aftermarket
clutch would be OK.
