doesn't that just piss ya right off!!!!! Cripes, I HATE to hear this happen to folks. Had my share of turd orders in the past and it's so frustrating.
Anyhoo - might try these places for steelies:
http://www.trudesignwheel.net/contact_info.html (this would be my first choice - have heard good stuff about these folks)
http://www.thewheelsmith.net/chevy_wheels.html
http://www.earlywheel.com/
http://www.stocktonwheel.com/index.php (although I've heard a few folks complain about these folks on the forum as well - including me...)
Good luck, hope you get it sorted out - i HATE dealing with turd companies.
