Im sure this question has been asked a million times.... I looked but couldnt find it already asked. My question is what belts do i need for a slp 25% underdrive crank pulley and a asp 32% overdrive alternator pulley. What size ac belt and what size regular pulley do i need.

I used to have the size for 25% under drive wrote down, but have lost it. I can look at my belt later today, but it's for the underdrive crank pulley and alternator pulley, both. Will that help you?

As long as it is the crank 25%under and the alternator32% over. It will be perfect if that is what you have. Thanks.
