Side note, has anyone figured out how to improve these rear spring hangers? The bolts were a nightmare to remove (cut them out with cutting disc and sawzall). Crap just piles up inside that cavity and rusts the nut to the bolt really bad. And since the bolt is guaranteed to be seized up in the bushing, it's impossible to get the nut off or hammer out the bolt.
Thought about cutting a hole in the backing plate to gain access to the nut and then welding up the top of the hanger to seal it from the elements
