Wheel stud Knurl size

[Hibbing_Coronet_500]

I ordered a Goodson wheel stud swedge cutter. I am going to go with longer wheel studs as I am running a 1/4 inch spacer on the front because the wheels have the wrong backspace.

My 67 has the 10" front drum. Anyone know the knurl diameter by chance?

After I get the 5 wheel studs changed out in the front. I will have a swedge cutter for sale.

Only 5?
The previous owner at sometime in history tried to remove the left handed thread wheel studs and ruined the hub.
So I only have 5 original wheel studs to remove.

Thanks in advance

Usually it goes by stud size and that would be 1/2"

Yeah, I have 1/2 x 20 studs
