Have a 91 yj w/ auto. 3sp, has to be the 904 or999, right? Mated to the np 231. Also have a 80 model CJ trans ad tcase. 904 and D300. My question is...does the 91 and 80 have the same tailshaft and spacing allowing the older trans to mate up to the np231? Also, does anyone have any suggestions as to where to buy a rebuild kit for same.??
