I wanted to follow up on what I did with the exhaust hanger.
I ended up needing 2 new exhaust hangers. The middle mount behind the cats was also broken. The exhaust had been changed at some point from the headers back and that's why nothing made sense and was McGeyvered. I used an exhaust clamp + exhaust hook that bolts to clamp + rubber hanger that connects to this aftermarket hook + stock hook on frame. The 2 hangers by the muffler were OK. In the rear by the tip, I had to make a hanger out of clamp + hook (bolted to clamp) + rubber + hook (bolted to body) as the body had no stock hook on it. I should have taken pictures of the result.
Unfortunately I also had to weld up the exhaust pipe between the cats and the muffler as there was a leak from the clamp holding the 2 pipes together. I tried 20 different positions for the clamp and it just kept leaking. I think one of the pipes had been slightly deformed from someone over tightening the clamp, etc.
