Rich, the Gearvendors is expensive, but you don't have to change axles and can eliminate the center bearing in the drive shaft due to the 20 1/2" length of the Gearvendors unit and use a single drive shaft. Unlike the Ranger overdrive you don't have to cut a hole in the floor for the shifter since the Gearvendors is electrically operated. I used the throttle knob on the dash remounted on a push-pull switch to activate it.
