When I bought my 93 the guy said it had underdrive pulleys on it. I have also had one person look and they said it didn't (kind of a moron though). Is there any difference in the kits that different companies sell. Let me know if I am wrong but the kits usually come with crank, water, and alternator pullies right? Oh, by difference in the kits, I mean in diameter. I am hoping to get rid of the a/c (broke) and the smog (no cats) and I have read many posts on belt size. I need a belt that fits the underdrive kit as well as fms a/c delete and smog pump bypass. Thanks
