A/C delete
 

I want to take off my a/c pump and put a pulley in its place, does anybody know if somebody makes a delete kit or something that will fit in its place.

Forgot to say, it's a 2001 Mazda Miata mx-5 with the 1.8L

All you should need is a shorter belt. I believe the steering pulley is the one that moves to tighten the belt, so just going shorter and tightening the belt should work fine.
