I am finally getting around to setting up the paxton mcculloch (vs57) on my 56 ECZ 292 motor, and need to get the right belt to drive the supercharger. I have a passenger car set up (mounts the blower in the middle above the timing cover) with the 7" crank pulley.
If you don't have one for sale,,,, maybe you could point me to a source?
