Looking good, must feel good to be paying dues to run
I looked for studs that fitted a "normal" sized drill bit, then decided to buy a 17/32 drill bit.
Figured it was better to have a drill bit that I hardly used than trying to search for oddball studs if I ever needed replacements.
I have a set of studs in my spares box in case I need them, they also fit my trailer hubs and probably a few other vehicles on the salt.
My 2 cents
