OK... I am getting a 4 point YJ cage for my cj7. 2 questions I need answered. 1) Is putting in sandwitch plates good ebnought for the cage attaching to the front floor board or do I need to tie it into the frame? I do not do much serious off roading or climbing. It is mostly a safety issue for my two boys who sit in the back on my cj. I am getting a smoking deal on a full cage! and question 2) will rear 3 point shoulder belts from a yj work in a cj? If so, are there modifications that need to be done to get the 3 point belts in the back? Iknow that was 3 questions.
