Powerbond 25% Underdrive pulley?

I have a QTP two peace timing cover and am installing a Powerbond 25% underdrive pulley which is supposed to be none underdriven AC to work with the QTP timing chain cover. Talked to vendor and they sold me PBU 1117-SS25. When I install it there is almost no clearance between the AC pulley and QTP timing chain cover. Stock AC pulley measures approx. 7.25", the Powerbond AC pulley measures approx 6". Anyone know the Powerbond pulley number for 25% underdriven and none underdriven AC?

Just threw away my box like last week! TSP has them, that's where I got mine. PM or email Matt he will let you know the number. They might have it listed on their site....

Looks like your part number is correct. this was on TSPs site about the pulley: Powerbond has recently changed the amount of underdrive for the air conditioner belt on this pulley. It used to be the stock size so your stock a/c belt would work, but they have recently made the change to 10% underdrive for the a/c side. They are shipping both models, so you will need to verify which a/c belt you will need once you receive the pulley. The main serpentine belt side of the pulley remains at 25% underdrive!

Are you using QTP two piece timing cover?
