underdrive pulley belt? So I just purchased a sfi summit underdrive pulley for my ls1 camaro. Does anyone know the two size belts I need. Summit lists a few different size belts and I am not too sure which ones I need. They list a 76in a 37.7 and a 40. I tried to cross reference the part numbers through autozone with no luck. If anyone has part numbers it would be great

I have an ati 10% in my sig and 40" is way to big for me so id tell u the 37 is right for you and the 76 also is correct for a 25% underdrive. at autozone i see 5060760 as the main belt number the "76" in the number is the size of the belt 
and for the a/c 370k4 is the number
and for the a/c 370k4 is the number
