Well...I purchased the truck with 30 spline longs installed. I would like to imagine the previous owner put in the hub gears as well....However, is there a marking, or a way to tell externally, that I actually have Longfield hub gears?
If not...I guess dropping the coin on a new set of hub gears is cheaper than new shafts...
if you have the previous owners name Bobby should be able to tell you if he purchased the hub gears.
