hi all,

i've had what turns out to be a belt chirp/squeal ( a while now and i'm finally about to just replace pretty much the whole drive belt & AC setup because i'm sick of it. I've read many conflicting posts, apparently there are some differences in part numbers between 97-00 and 01-04 models and I want to make sure I'm ordering the right stuff. it's for a 2003 z06 (LS6). i've been comparing stuff from ( and ( since i've read good stuff about the gatorback line, but i'm not sure which is corresponding part number on amazon.

are the idler pulleys for A/C and drive belt the same or do I need different idler pulleys? How about the tensioner pulleys?

so far I have:
- drive belt idler pulley: #49006 Goodyear Gatorback Idler and Tensioner Pulley (
- drive belt: #4060802 Goodyear Gatorback Poly-V Belts (
- A/C belt: #4040420 Goodyear Gatorback Poly-V Belts (

any input is appreciated. thanks!
