Here is one of the 4-Bar Bracket that I use on different projects. The material is .25 hot rolled steel Laser cut for tight tolerances. The axle tube hole is 3 inch. I will be selling these and others
This bracket is designed to fit 2x3 tubing. Now you can get all of the brackets for 3" round tube.
The rod end that I'm using are .75x16 thread grade 8 bolts. With Prothane bushings
The tubing is 1.25 DOM tubing
