In my 64 valiant there is no way I could squeeze a clutch in there. Between the fan & water pump is a 3/4 inch spacer and the fan is within 1/2 inch of the radiator.
Lose the spacer,and get the shortest clutch from Hayden.
The shortest clutch they have is for a Jaguar,I've used them on small blocks.
There is also 3 or 4 different spacer widths.
Like I said,I'm happy with the 4 blade fan,so I have never tried to make a clutch fan work on a slant. But here are some options.
Apparently you can make it work,because the OP is already using one.
