With some fabrication, you can make nearly any (about the same size) seat fit in a CJ. Some might cost you the fold-forward ability, as you would have to mount it, via custom mounts, to the floor. But will it fit a CJ bracket, I don't know.
I don't think a Cherokee dash will fit, it's wider and curved, unlike the strait and shallow CJ dash.
