Probably anyone of a dozen different aftermark companies can supply most of the body parts as it looks pretty standard to me with offset wheels etc. Of course I am not a connisour of GM trucks either and they all look pretty much the same to me since the last make over a bunch of years ago. Don't get me wrong I am not bashing it or anything and I really have no brand loyalty either I just buy what has the best price and performance for what I need to do.
