Like the title says I'm looking for someone to tell me what size belt to use. I have searched but cant find an exact size. For a gen 1 whipple with a 3.1 upper 4lb lower and a 100mm idler. The closest I come up is 79-80inch belt. thanks
What I do is find something close and check with napa to see if it is in stock or one close to the one you think you need. Test fit it and go from there.
