TJ tranny shifters are situation towards the back of the transmission. with a SM 465 its obviously located much farther foward. I had to bend my T-18 shift handle using the heat from a cutting torch to fit in my YJ so it wasn't hitting the dash in 1st gear. You can also cut a few inches off the top of the shift handle and weld on a new threaded stud to shorten the throw of the shifter. A SM465 handle is gonna be sticking way higher then a stock shifter.
