ASP Over Drive Alternator Pulley I am running a 25% underdrive pulley ordered an ASP Over-drive pulley today but they said I will need to find a nut for it because it has a clutch pulley. As far as I can tell it's not a clutch Pulley it's a regular bolt on Pulley. Can you guys tell me what size nut you used or if the stock was fine and what belt size you ended up using?

I picked up an alternator nut from my local mechanic. He had a box full of them. As far as the belt length, best to ask ASP for a length. Probably 1/4-1/2" shorter than your current belt. If your current belt is almost too short now might not even need another belt.

You can calculate belt length change by the difference of the two circumferences. If the belt wraps around the alternator pulley 180* then the belt difference would be half the difference of the two circumferences. With a 90* wrap then use 1/4.
