I've used Classic Parts of America (Chevy Duty) and Jim Carter, which hasn't been mentioned yet. I think I may be done with Chevy Duty. I'm not going into it right now, but they screwed up on the bed wood that I ordered from them. Jim Carter seems to be a tad more expensive than Chevy Duty, but they also seem to be a little more knowledgeable. The stuff that I've ordered from them has always been exactly as advertised.
