Guess I'm just on the wrong end of the receiving line Matt. After spending about an hour looking through their site, I still can't find a real price for the OD at Gear Vendors, only a price range. Starting at a low of $2,795 and running up to $4,995 that's a tad to rich for my blood. On top of that it looks like there would have to be some extensive modification to my 1950, 3/4 ton drive line. Don't know how you would approach cutting the front torque tube and splined drive shaft down to fit but I do know your looking at a lot of work to get that right.
All in all, an overdrive unit from GV looks to me to be out of reach for most everyone except the upper crust where price would not be an object.
