Maybe we don't understand the question. What are you trying to do? Fit a locking hub from a different vehicle? The hub diameter and the stud size are the same whether it is a 1965 FJ40 or a 1997 FZJ80. Hubs from a Suzuki Samurai, Ford Courier, and Isuzu Amigo will bolt on as they have the same size, but the splined part that the CV axle (birfield) fits into are all different.
I'm getting some custom rims made and the guy needs to know the diameter for the hub and the size of studs used to burn the holes out. I have a 76 FJ40 Land Cruiser like i posted before. Thanks again tho.
