How did you limit your suspension. That may be what I end up doing.
I welded and then tapped a plate on top of the LCA and added a Just Suspension bumper that I located at the parts store. It is relatively flat and has a threaded rod that screws onto the plate. I then stacked fender washers underneath it to fine tune the distance the suspension travels up when the car lands. On the top I built a bracket that is attached to the cage I have an industrial type I bolt installed that is connected to a chain. It is then attached to the upper control arm.
I have attempted to add a couple of pictures. I hope they work!
