Tractor heims and 1.75x.120 dom and some dodge spring bushings and 1.25x.120 dom.
I did trim the bottom of the axle tabs off so it doesn't hang down below the axle truss. Just hadn't gotten to it when I took those pictures.
2x2x.120 for the crossmember.
Another spring bushing for the bottom of the shackle.
The bracket was a little less than I wanted it to be - the 1/4" plate was a little thin, and the "rib" left after I hole-sawed the 2.75" hole for the mounting around the axle tube was too thin, and I tore it off after a couple of races.
Does it's job, though. Got rid of the bad wheel hop when I'm wot.
Mine is similar to toms except I used the ruff stuff brackets
Then I sleaved 1.5 tube with 1.75 tube. Plug welded and everything is welded to the bushing ends. 3/4x3/4 high miss rod end at the frame. Shorty shackle was used for that.
It was painted a few days later, done by tractractor offroad with blue torch fab brackets. It's served me well, and kept me from breaking u-joints, leaf springs and yokes. All of which were getting trashed when the axle wrapped.
