I am buying a dana 60 from a guy local and the truck has a 14bff C&C model in the rear. It is a old military truck. Should I grab the shafts and carrier from the 14bff while I can for spares? I know that the shafts should fit (info from pirate). The 14bff that I am buying has 4.10s in it and so does this truck. I dont know if the rear has a locker in it or not.
