Hey Wes, I still have the original axles from the YJ, that came off of a Grand Wagoneer. That would look really good under that CJ, as they have narrow axles. The front axle is a D44, and a AMC 20 one piece for the rear. I would be more than glad to trade them, for some paint on the YJ........lol. As far as TX emissions, no sniff test for anything older than 20-25 yrs. As long as everything else works, it will pass.
