IMHO a roll bar that isn't tied into the frame isn't anything. My 46 willys had a full cage done by a shop that built race cars. It was worth it, as my oldest son tried it out.

I had a 75 Cj5 first and sold it. It had a factory bar but it wasn't much more than a decoration. My second was a 76 years later and the factory bar went down the road in favor of a cage. It was a kit, and tying it into the frame wasn't bad.
