Zert nuts, might have been an easier fix! I've run the T-18 /D 20 combo, for years. Several years back, installed the Don Custer Twin Stick. It's Much easier to use & shift, than the Single Factory shifter. I still get bind sometimes in 4 low. If it doesn't want to "rock out", I just hop out & unlock a hub, or two. Releases the bind, & slips right out.
