So after a lot of delays I have collected some parts and received material.
I am using 2x3x.125
springs from a YJ.
Will order a axel 2000lbs once everything is together.
rims and rubber off my now gone MJ
I started building a frame but after a lot of looking and thinking I did not like the location of the cross beams so I ground all the tack's off and moved them.
What I got so far for the frame. once I have the axel I will locate the rear cross support and the middle one so they will be in the right place for the shocks.
I had to make plats to cover factory holes in the MJ box supports. I drilled and put tread inserts in to bold the box to the frame I want to be able to separate the two for future modifications and repairs
The inserts and tool to install them. they simple to use.
Drill the hole to the size according to the chart, drop the insert in, you may have to tap with tap hammer. using a wrench you hold one part of the tool and using a socket with the allen key in the kit screw it down till it is tight. the directions give to a torque spec. the insert crushes pinching itself to the material you drilled into.
