    Forgive me if these were posted elsewhere but I didn't find a reference in a search. The flanges in this case are the 27 spline versions but assuming the 10 spline ones have the same thickness, the ARP bolts should work equally well on both. In preparation, I ran a 3/8-16 bottoming tap in all hub holes. Note the shoulder length for the counter bore in the hubs. Just about perfect. A nice snug fit with 180k psi bolts. One can also see the bolt heads and required paired washers extend slightly past the lip of the drive flange. My MT wheels still slipped right on, including the center cap. The torque on these is 45 ft-lbs.

    Nice - brings back memories.... I spent a lot of time deep in the muck swapping the hubs out as a kid before dad finally got selectable hubs. Then I spent a long time with a hack saw cutting the threads off the end of the axle to get them to fit :)
