Wheel stud knurl diameters

Yep, 62 savoy, with the wheels and tires to go on my rr on it temporarily. Those are 67 barracuda hubcaps. I don't know if you know, but there are two different sizes of poverty caps, generally called 9" and 10" . The early caps are 10" (pre 66). The caps have to match the wheel centers.
The 62 usually wears centerlines or torque thrusts with slicks.
