I want to fab up a new rear shackle hanger so I can get my 55 springs onto my 40. Instead of flipping the stock hanger, I plan on making one with Rubicon Express Superflex joints. IIRC the larger joint has a body width of 2 5/8" which should be just about perfect. I figure some 2 - 2.25 box tubing and a hole saw and I shouild be good to go. Anyone else do this or consider it?
