I've also used www.partszoneonline.com
It's P&G Chevy out of PA. They have a phone # so you could actually talk to somebody and verify the part you want and check availability. Their shipping is less then parts direct and they ship same or next day.

I'll second P&G. http://www.partszoneonline.com/contactUs.html Last time I called up Bill Sr on a Thursday, gave him my CC# & emailed him a list of things. Everything showed up here on Tuesday. I've had several flawless orders from them. Like was said before, they don't rip ya on shipping...
