Just went ffrom my ASP under drive pullley to an ATI 10% U/D crank pulley.

The accessory belts are too small. I haven't tried the stock ones but heard they are too big.

What size is everyone using?

Thanks

If you list your pulley size bob @ EPP should be able to tell you what belt size you need.

Thanks Bob,

Checked two auto parts stores and they didn't have the exact part numbers. Haven't got around to test fitting them yet but got the following:

37.7 and 77.5 Gatorback
39.5 and 79 Dayco

Do you think either of these combos will work?

I don't know which ones would be the closest, as it would just be a guess. Here is Napa's guide for looking for other manufacturers part numbers. http://www.napatirehardware.com/down...IDE_FORWEB.pdf
