Ok i have a set of ford dana 60 hubs and i need to know if they will work on early model ford king pin 60's and late model ford BJ 60's...the studs measure 1/2 across...(i think this is how you measure studs) hear are a couple of pics....basicly what will they fit.

Although I can't speak from experiance on the balljoint 60s, the 78-79 60 does have 1/2" studs. My dad's 89 F250 uses 9/16" studs, so I would assume the F350s would be the same. Yeah, yeah, I've assumed stuff before, so take it with a grain of salt.

Other than stud size, they *look* very similar to my 78 D60 rotors, FWIW

can anyone confirm?

Far as I can remember hubs for a 60 is a hub for a 60 it shouldnt matter what year. If your wondering see if the stub shaft fits the splines it should and make sure it fits the in the rotor assembly if it does good to go

As long as they are D60 hubs you can use them on either D60, and also on the D50 TTB. 79 and older 250/350 will have 1/2" studs, 80+ will have 9/16 studs.
