KH brakes, stud size?

[JR]

I found a new pair of rotors on ebay for the KH setup that Im installing on the 72 but I need to reuse the hubs. It looks like all I have to do is pound out the stock studs so that the hubs come off the rotors. What size are the studs? I want to get a new set of them and have them ready when the new rotors get here.

The studs you need are NAPA part number BK6413148 for RH and
BK6414089 for LH. The RH is head stamped 130 and the LH is head stamped 131. Overall length is 2" and the shoulder length is 1 1/16". with a 7/16"-20 thread size. Hope this helps. :thumbup:

Is there a way to upgrade these studs to a 1/2" size? My understanding is that the hubs are similar to those used on '66-'69 B-body disc brakes.
