God created acetylene wrenches and pop-rivet tools so you can put any engine in any car. Heck, I built up four Corvette-powered Austin Healeys. The one I built for me was 2,350 pounds with hard top, roll bar and full tank of gas--and 350 hp.
Mr. Jeep doesn't care *what* transmission the engine wears. That's why adapter-plates were invented. Quality trasmissions are unconcerned as to what they're hiding behind, as well. The possibilities are endless.
A variation on David Scott's theme is that *nobody* car-jacks old stuff. "Great car!" doesn't necessarily mean a high-dollar shiny look.
