Other ways to attach roll bar to Fiberglass body

I have a 1985 CJ7 and I am looking to replace the custom steel roll bar mounts that bolt through the rear wheel well. I'm sure others have run into this situation where the steel is no longer what it used to be due to rust and rot. I am wondering what others have done to get these roll bars mounted. I am open to all suggestions, I just need some ideas.

Hi again, just saw this post. Think of it this way. You need to make a sandwich out of the body. The roll bar plate that bolts down it down is the top piece of bread. Your fiberglass body is the meat. Then a plate goes under the body and four bolts run through and it attaches it to the plate the roll bar is welded to.

Then you take the bottom plate and use a piece of DOM tubing and weld it to the bottom plate then to the frame.

This is actually the only way to have an actual safe roll cage or bar. It needs to be anchored to the frame even if you have a steel body although its not as necessary. If its just bolted to the body you run the risk of tearing the roll bar off the body if you have an exceptionally bad roll, or worse, punching through the body and being crushed.

Here is an example of the plates.

Jeep CJ YJ Roll Cage Plate Kit | Roll Cages & Mounting Plates | WFOConcepts.com

I purchased a whole bunch from another company for my cage when I get around to it but they all do the same thing. Anchor your frame to your roll cage.

I have my old CJ7 roll cage at my folks place if you want it. I have been looking to get rid of it. I wouldn't give it to you as it sits as some of the welds will have to be ground down and addressed again. They aren't especially terrible but I wouldn't give someone a cage without it being sound. But you would still need to tie the cage into your frame especially since you have a fiberglass body.

My old cage also not fit a hard top on top of it and neither do i think it will work will full doors.
