It soundslike he removed the front driveshaft to save on fuel mileage as i once did when i had Quadratrac. The font diff is still spinning however as they dont (normally) have lockout hubs.
I think i still have my old front driveshaft if you need one. It is in peices and cleaned and painted so it will need to be built, it is the cv joint type and is in sound condition the pin is not worn,and was out of an automatic, i dont know if that makes a difference or not, maybe someone on this board knows? $50. bucks if you want it.
