What what I remember in the little bit of reseach I did, was the YJ and TJ dana 30s and 44s have the upper ball joint higher than the older CJ dana 30 and older 44s....so its not a bolt on as the inner knuckles would have to be cut off and the older style welded on....to much BS for most... But a TJ with a front 44 and real locking hubs would appeal to me..
