Budnik stud size

[Clockwork]

What size stud does Budnik typically make their wheels for, 7/16 5/8 1/2? I'm using 7/16 studs with acorn style lugs and the fit is a bit sloppy until the lugs seat. I want to upgrade my axles and need to know what size studs to order with them.
Would 5/8 or other be better with acorn lugs?
My car is in storage and I can't measure right now.

Thanks

Dean, Budnik drills the wheels when you order. Did you buy them new? If you told them you were running stock suspension then, yes 7/16

It's a standard 60 degree conical seat (pretty much industry standard) so any size from 7/16, 1/2, 12x1.5 etc. is right on. Most 5/8 hardware we came across was a nut and washer style like the Mark Williams hardware, which will require a much different style lug seat then what you budnik's are drilled to accomodate. Unless of course you told them ahead of time about it. 5/8's stuff is way overkill though.
