I have sceen one or two trans overdrives with a couple diferent versions, maybe with luck ranger might have one. I think it was a t6 or something like that, think he said they used them in vets. Maybe it was trimex, they had 5 and 6 speeds - they had about three different choices to move the shifter. Just a thought, the ranger sounds neat. How much do they run, do they have a web site? I dont need one now, but its interesting good luck.
