i've had what turns out to be a belt chirp/squeal 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 and amazon.com 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?
