I ground down the R gate on my AW4 shifter until I had it where I wanted it. I made it harder to push than the other gears but it's still easy enough to do it quickly.
RADesigns rock shifter is an awesome upgrade for the aw4
Winters/Art Carr shifters, reverse manual valve body so Reverse is a short skip over Neutral from 1st gear. Grind out the gate to get into reverse quick.
