If you want a thinner nut CJPP has one: http://www.cjponyparts.com/jam-nut-shift-ball-12mm-x-125-2005-2013/p/HW3047/
Dumb question: Do I just crank the nut down low enough that I can still use reverse then pop the knob ontop of that?
Gave my dad his explorer back and got the GT out of their garage and back into mine. Got a guy coming from lexington to sell me his 04 grand cherokee 4wd so I don't have to take my precious out in the frozen hell anymore.
