Willwood stud size larger than stock??

I just installed a set of 13" rotors and 6 piston calipers on my 69 Camaro. The studs on the spindle are larger than my stock lugs. Anyone know what Willwood uses for stud size? Thanks.

just guessing but probably 1/2 x 20... I believe thats the upgrade I have (not willwood though)
