I machine ARP studs to size including the flange thickness to knurl. I don't know if you will find exactly what you want.

curious.
I thought studs where pretty standard by dia and thread pitch and length?
the splinded part is per diam and also standard.
not sure I understand the issue

You will not find what you need as an R&R install.......I bought the Moroso 46150 and drilled my hubs on a drill press...carefully.

NOTE- these are 1/2-20 studs which I use in the 31 spline HD axles. Same procedure though for 7/16 studs

I also used ARP 100-7701. These are 7/16 x 20, same nut size as original. Gary is showing 1/2" x 20 which is a stronger, which will require new nuts.
The knurl size on the 7701 is a bit larger than the stock studs. Like Jebby says, the holes need to be slightly larger.
I used a 15/32" drill bit to enlarge the holes slightly, with a "jig" to ensure a straight hole.
