I bought gatorback belts a few weeks ago from autozone. I think the total came out to be roughly $45. If you buy gatorbacks you need 4040405 and i believe 4060760. Might want to double check on the 760 but i am sure about the 4040405 for your ac belt. Although this is for an LS2 don't think it differs though.
