Working on a 69 2a (88); Seeking help with what exact size drill bit to use to drill out the stripped threads in the hub from older screw-in type stud to enable a new press-in 1/2" stud (PLC405 R.N. part number). The new press-in stud has an outside diameter of 0.5825" at the mid-point of the splined end that presses-into the stud hole. The lug nut threads are 0.5555 O.D. I assume I'm looking for a few thousand's less diameter than the splines for a tight fit. I plan to use washers, a box wrench or buy one of those special pull through tools.
Looking at drill bit charts a 37/64 (0.5781") appears it would be close?
