I had a buddy that had this same problem when he did his body lift. You can either cut and weld in one of those "lifts" or what my buddy did was grind the shifter plate notches for those gears out a little bit to allow the shifter to move forward further and fully engage those gears.I put a body lift on my 86 and I need to locate/figure out a way to lift the shifter up. Being that the shifter is lower in the truck, it is not liking going into 2nd and 4th gear. I thought I saw something in a thread somewhere on here but I can't locate it. Thanks all!
