Dave -

Here's one; fan clutch is the same as non-A/C.

Re: 1967 Corvette SB, AC Fan/ Fan Clutch

John's right, no difference in fan clutch based on A/C option for your year. Plus, as the JG book states, there were two active fan clutch suppliers (Eaton and Schwitzer) that were used on a rather random basis at the factory. The only difference was SB vs. BB and that dictated the shaft length of the fan clutch.

So, there's no 'correct' fan clutch for your car. It need to have the right shaft length based on SB vs. BB and can be EITHER an Eaton coil unit or a Schwitzer bar device.

The 66-67 Corvettes 327 w/AC were issued two different 18" 5-blade fans on the assembly line.

1. GM # 3789562 made by Hayes-Albion (stamped "H", "FRONT", and "W" on the back side) with 4 rivets/blade on arrowhead shaped attaching arms.

2. GM # 3863137 made by Schwitzer (stamped "912239", the Schwitzer part number, and a date code on the blades). The picture in John's post #3 is of the Schwitzer fan.
