Series II Supercharger Belt

Is the Supercharger belt for a GP Series II the same as what is on my Bonneville Series II S/C? If not im going to be pissed... :x

I can't say %100 but because they both have the same engine (just differnt accessories around it like PCM's) It should be an exact fit.

No, G and H-bodies use much longer supercharger belts than W-bodies.

A GP supercharger belt is 4060660 stock, whereas a Bonneviile is 4060725. The coil bracket is different (about 20lbs. lighter on the bonneville) and the coil bracket is what the tensioner is mounted to, so the tensioner ends up being in a different spot, making the need for the belt to be longer. But the bonneviile's belt wraps around the supercharger pulley more.
