If you get a forward shift G52,G54, or certain W56's, your shifters will nut move but your tranny mount will need to be moved. I just put a G54 in my 83 replacing my L52. the shifters are in the same location as the L52 but the tranny is a few inches longerbetween the bell housing and T case I had too move my T case mount a few inches. I welded my crossmember on as a temp fix while I make a new mount. The nice thing about the forward shift is your shifters are in the same location but you get a few more inches for your driveline angle, and save some space on your floor board if you do dual cases.
