Belt Help... Figured I'd post this here with all the FI guru's around... 
Does anyone have any idea what size belts (part #'s if you have em) are needed using the supplied ATI crank pulley using all the stock accessories??
I have gone from the ATI (different company) super damper underdrive pulley to the ATI Procharger supplied pulley so of course the belt I had used for the A/C and the belt for the other accessories are too short.
Would the stock size belts work with the ATI supplied pulley? Thanks!

The last 4 digits of the belt part numbers are usually their length in mm. They are usually available in 10-15 mm increments. So if yours has 4 numbers like 1250, have them look up the 1260, 1275, 1305, 1315, etc. I usually make an estimated length holding up the short belt, then go get that size plus the next 4 sizes available. Only did I end up without a belt that fit. Take back the ones that aren't right. They vary a lot in price between sizes, too from like $22 to $37.
I doubt you'll get lucky with the stock belt, but it's worth checking...
