Thanks!
That gets me a lot closer.
You win the arcane knowledge link of the day award.
If I stay at 7/16 thread I can take up half of the shifted off-set diameter.
Original .517".ARP .580"
Ideal would be .640".
So .060" shy of ideal but still fully supporting the flange at the head of the stud.

UPC: 672036000400
Wheel Stud Style: Press-in
Wheel Stud Thread Size: 7/16-20 in. RH
Knurl Diameter (in.): 0.580 in.

Knurl Length (in): 0.300 in.
Quick-Start Nose: Yes

If I go to 1/2" stud I can get more than enough knurl support.
Going to mag wheels so 1/2" stud is probably fine to use.

Ideal would be .640".
I don't think .015" would be an issue in the real world.
Knowing the OE use I can probably get these individually at NAPA or at least look at examples.
