hi all,

i've had what turns out to be a belt chirp/squeal (http://tinyurl.com/7l6p5su)for 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 gmpartshouse.com (http://store.gmpartshouse.com/parts/2003/CHEVROLET/CORVETTE/Z06/?siteid=214638&vehicleid=1410422&section=COOLING%20SYSTEM&group=COOLING&subgroup=BELTS%20%26%20PULLEYS) and amazon.com (http://www.amazon.com/gp/part-finder/slide-show/2003/Chevrolet/Corvette?ie=UTF8&Model=Corvette%7C440&Make=Chevrolet%7C47&Year=2003%7C2003&partsNode=15721321&carId=002) 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 (http://www.amazon.com/gp/product/B000C30J7O/ref=oh_details_o00_s00_i00)
- drive belt: #4060802 Goodyear Gatorback Poly-V Belts (http://www.amazon.com/gp/product/B000C36BK8/ref=oh_details_o01_s00_i00)
- A/C belt: #4040420 Goodyear Gatorback Poly-V Belts (http://www.amazon.com/gp/product/B000C30IPW/ref=ox_sc_act_title_1?ie=UTF8&m=A139T64LTDCRO8)

any input is appreciated. thanks!
