Well I just ordered my first items from LMC (hood braces) and I know I'll be ticked if the crap is made in Japan, because LMC puts the American flag in some form on each cover of their catalog and seems to really stress "USA." I just wanted to mention that, I can't offer much help to your problem because I have never dealt with CHEVYDUTY before. If you're wanting to buy sheet metal, I would suggest a company called TABCO. They make good quality materials and are made in the USA. I have never personally dealt with them, but a very good friend of mine restores classic trucks and Blazers for a living/hobby (he's retired from the factory) and he uses TABCO for all his sheet metal. He's showed me their sheet metal compared to LMC's. TABCO's is about twice as thick and just seems more all-around durable. If you want some info regarding TABCO, just reply to this or shoot me a PM and I'll tell you how to get a catalog.
