Alternator pulley stock dia size needed

[curtis]

I measured a bunch I have here and got them from 54mm up to 71 mm dia. (measurement at the top of the v's ) Reason I'm asking is I'm doing a subaru alternator modded for use on a VR4 and was just wondering what stock belt size is. I know the smaller will charge better and is what came on the subaru already but was just wondering about belt size. So if you have a extra on the shelf hook a brother up. Thanks.
