what trans does he have? you need to know what v6 you have. Kaiser era v6 used a buick bellhousing bolt pattern and does not bolt to AMC era trans. if you have a 72 v6 you can use a AMC trans, anything earlier than that, you cant use amc trans. your engine could also be a odd or even fire engine and you will want to know which. if you can post the engine ID number I will it up. 70-75 were blurry years for jeep due to AMC buying Kaiser. Lots of left over and new parts were used during that transition period. so to sum it up, you need to no if you have a AMC era engine or not
