CJ7 Rear Shock mounting Options

Hey guys slow building my CJ7

Finally getting around to doing my rear shocks. I'm running what I think to be 4" RE springs SUA with my waggy axles. I continually knock the rear shocks off the lower mounts off the spring plates and I've ruined two shocks already.

I'm looking into welding up some RuffStuff Specialties Monster Axle sidemount shock brackets (Monster Axle Sidemount Shock Bracket, Pair - RuffStuff Specialties) to the front of the axle to get the lower mounts up out of the way.

There's limited space and I don't want to use the factory upper mounts as my shocks become very short, nor go through the tub for the upper mounts. So I'm thinking of running them at angles like so: / \ with the upper mounts standing off an additional cross beam between the frame rails close to center of the tub. To get any decent length I'm looking at close to 45-50* inboard (90* being vertical) and little to no angle front to back.

How much is too much angle for the shock to so it's job? I measured quickly and 19-20" ride height shock length is what I'm coming up with the lower mounts mocked up just inside the rear springs. I'm looking at the Bilstein 5125's Part #33-186542 with 9.24" travel, 15.1" compressed, 24.3" extended @ 255/70 valving.

Is there a better way to do this?
School me please...

Edit*** after some more searching I saw another guy go more forward and longer with the upper mount but he also had a BL and room to do so.

you need to be mindful of the angle of the shocks. the more angle the less dampening the more body roll. had the shocks on my scrambler angled to far and it SUCKED !!!

Chef, that's what I'm asking. How much is too much? I realize that at too much of an angle there's not going to be as much stroke with upward and downward movement with less dampening.

I've been running with no shocks in the back for the last year, DD'ing. Body roll isn't much of a problem but speed bumps and potholes is gonna cost me some dental work and a trip to the chiropractor soon lol.

The CJ isn't real flexy as it is or anything, but I don't want my shocks to limit what travel in the rear I do have.

you know, I hadn't really considered going outside the frame rails in the rear. There's not a lot of room but it might work since the springs are sill under the frame and the axle is a little wider than stock.

I'm at work but I just went out and looked again for possible outside the frame rail mounting, like the front using Ford shock towers and it COULD work. I would have to cut out a chunk off the back of the Ford towers and almost flush the mount up against the tub on the inside of the wheel well. The skinny bilsteins would be the way to go keeping the tubes as close to the frame as possible otherwise, with much articulation there might be contact with the tire on the full stuff side. it'll still be close.
