Front is open, they did come from a junkyard. I have not run them. There is a little slack in the pinion of the 60, the pinion seal was bad and leaking oil. I replaced the seal and looked at the outer pinion bearing and it looked ok. I have removed the covers on both axles to verify gearing and check everything out, everything looks fine. Like I said before, the brakes on the 60 look new as well as the rotors. The calipers and hoses are there also. The spring perches on the 14bff will have to be relocated to fit anything other than a 1 ton. I also have the u-bolt plates for the 60.
