I am sure they would work on a Cherokee as well
Yep, and you can do your own too.
I used belts out of the front of some big '70's Buick, well, back when I had a rear seat.
There are captive nuts up above the headliner about 4-5" behind the rear seat.
I had to fab a couple of backing plates where they go into the rear fender areas but it was comforting to know folks were in there securely.
