I recently had Marlin do this on my 1990 extracab and I'm very happy with it. The length is the same so the crossmember doesn't need anything. However the shifter is off a little requiring the floorboard hole to be enlarged and the shifter to be jogged over. I'm not a techie so sorry this isn't very precise. I had him put a short throw kit on at the same time. Hope this helps...
