I have a 1990 G20 350 5.7L and am looking for an AC compressor bypass pulley and/or shorter serpentine belt and have been coming up short. do i need a special pulley for where the AC was or are there shorter belts that will do the trick?

Seems like a good time to do this because I'm Pulling engine today for various reasons. Last spring i had to pull the AC unit from under the hood due to hitting someone that pulled out in front of me. The plastic casing was all busted up and mashed against the coolant reservoir. Someday I'll get a new quarter panel and straighten everything out so the AC can fit but it will require welding and i can't do any of that (yet) nor afford it at the moment. So looking to simplify things.
