I think your shifter throw lever (with the nylon bush on the end) is to long with out using the proper spacer that comes with the short throw shifter kit, and this allowed the bush to come out the bottom of the round hole it operates in, causing a bind on the selector while trying to select a gear.
One you push the gear lever/nylon bushing out the bottom of it's hole, the bushing pivots all around, and is
very hard to get it to stay strait up and down, allowing you to slide that puppy out. You just have to do a lot of gentle wiggling to get it to line up so it will ease out.
