Baloney. The main lesson is that a well-known rear end place with a good reputation, and that I paid a significant amount of money to do it right, screwed up! This is a routine job for them and I should not have to follow along second-guessing the professionals. Weld the perches, weld the back brace, then put the housing ends on, and everything lines up. But thanks for the victim-blaming.
