Friends, I need to order wheel studs for the front of my TR3 using stock hubs. I'm looking for a longer length to match my rear studs. B I have the Southwick axle. B What is the diameter of the knurled part on a stock stud? B Or What is the diameter of the stud hole on the stock hub? Man, that got confusing! Todd Redmond 1958 Triumph TR3aB
