For ATI Part #918857 I used NAPA Belt #25-060560. This Belt was recommended by others here on the forum who did the install prior to doing it myself. All is good here!!

Thanks, also does it come with a bolt or do we need to buy another or reuse stock?

Yw
Does not come with a bolt. Do not reuse stock. Buy a replacement stock OEM Crank bolt, or an ARP bolt #234-2503. The stock bolt washer/flange will need to be ground down a hair to fit in the ATI UDP.
