Well, after buying 3 belts I finally got the one that fits. I have an ATI Super Dampener, stock idle pully, 1le ac delete pully, stock ps pump and a 200amp Mr.alternator alt with a hotrod line chrome pully,fan,guard....the pully seems alittle smaller then the stocker....I tried gatorback belt part number 4060642 & 4060635 they were both wayy to big, prob becuase of the smaller alternator pully. I ended up buying 4060625 and it fit perfectly. Got it at autozone, they had to speical order it, and it was about $14 i think....i culd have saved ALOT of trouble if i just put the dam tape messure on the motor and routed is around how the belt is supposed to and get the size, HAHA o well, $45 later :-)
