Oh, and apparently GM has a TSB out for this, REALLY, what another JOKE!!. Do they really think they can resolve the entire chassis, NO WAY IN HELL THIS CAN BE DONE RIGHT with a tubed chassis or not removing the cab, drive line and tons of other components, etc. Just think about what is happening inside the tubed part of the chassis where you cant where water and salts will lay, add the oxygen and booyah you got lots of rust. Clearly shows GM engineers don't think, but they do got good slogans to think about and promote.
