Swap "family" style bar for "sport" style?

I have a '90 YJ, which has the sport style roll bar. Does anyone know if the later model YJ family style roll bar is a direct bolt in replacement? Are there additional seat belt mounts in the tub also, or would the 3 point belts bolt right in? The reason I am considering this is I have kids in booster seats, that require a 3 point belt.

Some of the mounting holes may have to be opened up a bit, but it will bolt in. Upper part of the rear belts, bolt to the roll bar and the lowers go to the same current location (to the best of my knowledge). Lots of guys have done it, and I will be doing it eventually but so far just researching it.

This is a very common swap - I'm surprised that only one person replied to you.
You can search for "roll bar swap" or any other variation of that and find a miltitude of threads/posts on the subject, some will even contain pictures... I've seen them before.
I know some people have to open the mounting holes in the bar plates a little, but some have claimed a perfect swap with nothing but some bolt spinning required.

I had to enlarge 2 holes slightly, but otherwise a direct swap. Timatoe is correct, the shoulder belt and retractor attach to the new bars.

You will have to drill one hole in the verticle part of each of the rear fenders to mount the fixed end of the rear seat belts shoulder strap. You might have to enlarge some of the bolt holes in the pads that mount to the floor behind the front seats. The front spreader bars might have to be adjusted by loosening the safety torx bolt in the top of them. Overall its an easy swap to do. Just try to get the male half of the rear seat belts when you buy the family style roll bar. All of the other seatbelt parts from you 90 will work with the newer roll bar.

I've been in this rut plenty long enough, I know what to expect. Weather my day is hell, or weather it goes well is kind of up to me I guess.

Thanks for the info guys. I will put that on my list of things to look for at the salvage yard next time I get to go. Today would have been a good day (nice weather), but I missed their hours. Next weekend is Valentines, which might not be the smartest time to go to the salvage yard. Gotta keep the honey happy.

I just completed this swap. It was just as the others described...had to open up two holes (one in each front plate). I used a step-bit (varibit...whatever they're called) to drill a new hole and the a rotary file to finish it.

I haven't put the 3-point belt in yet but will do so this weekend. I want to find a way to secure the end to the tub in a way that would hold up in the event of a crash...I just cringe at the thought of a bolt ripping right through the tub. I'd like to take a look at a stock YJ to see how the factory did this. Anyone have a good picture?
