As time goes by I've lost a lot of brain cells but if my memory serves me well, HURST used to make a shifter for 1955-57 Chevy cars with 4 speed trans. and bench seat. It was made to come forward to clear the seat before becoming vertical to meet your hand. The shifter would work on a T-10 or Muncie (and maybe a Saginaw) by using the correct mount and shifting rods/arms. This just might work in an AD truck. Nobody every throws away a good Hurst shifter so there has to be one out there somewhere. Hope this helps.
If I'm wrong please call my doctor so he can adjust my meds.
