I've gotten a few questions about this so I thought I would post a quick thread on the swap.
I took some vacation time a few weeks ago and did a little work on the Jeep. Just a little project that I had wanted to do for a while but never got around to. I wanted to beef up the back of the frame, add some good recovery points, improve the departure angle, and setup for a future wheelbase stretch.
Here is a before pic with the rear bumper on. This bumper is now the rear frame cross-member
I started off removing everything from the rear of the frame. I tried to save the stock cross-member for a friend but there was no way I could find to cut all the welds so I just chopped it.
welded nuts inside the frame for CJ style shackle hangers
and inside the bumper for future XJ spring stretch.
Here is the bumper mocked up on the frame. Marked for d-ring mounts as well
The JKS slickrock hanger bolted in place. These things are major beef!
and on the far side you can see how the mounts will be run for XJ springs when the time comes.
and here its all welded up, d-ring mounts installed (weld through), added some additional bracing from the frame around the recovery points. I turned the bumper around backwards to get the receiver hitch in closer (I tested to make sure a hitch would still work this way first).
The shackles pictured are too long. Tonight I installed a pair from Copperhead that are about 1.5" shorter and the ride height looks just right. I'll get it out of the garage and get some finished pics this weekend.
It actually looks like he may have skipped that step LOL. All you would need to do with his setup is not box in the ends and you could run a bolt straight up to the body mount. If you look at his pics, you can see the outer corners where the bolt was mounted and his bumper sits right under them.
If you did the crossmember so that it sat outside the tub edge, you could just make a tab on the inside of the bumer out of the scrap from making the bumper and mount it similar to the mid body frame mounts.

Thanks guys. Rusty the rear cross member is not close enough to run a bolt straight through the cross member but too close to run a truss from it for the body mount.
ERock someone else suggested the same thing. I have been waiting to tie my rear cage to the frame untill I did my stretch which is why I am doing the cross member fab. I guess I will go that route.
Just a little worried I would not have time to tie everything up before next run.
Hey Erock is that the same Jeep as you have always had? Last picture I can remember the body was in pretty bad shape.
