On my last xj, I cut mine off to repair the rust, and made new ones from 3/16 diamond plate, and replaced that part of the floor with some what thicker sheet metal. I also welded in a triangle piece on the front from the hanger to the subframe. No pics, but I might be able to get the new owner to send one...
I had to do this because the whole hanger rusted off the body on the passenger side, and the spring eye punched up through the rusty floor. The only way I even noticed was the jeep leaning so far that the tire was rubbing. I'll not be buying anymore jeeps from Pennsylvania, haha.
By the time I sold it, I had to cut off or replace the entire bottom 6" of the car, other than the frame rails.
It's now a dedicated trail pig.
