Ichiba studs knurl pattern? Need to replace with ARP

[Pstl_pete]

Does anyone know the knurl pattern on the Ichiba front and rear 5-lug conversion hubs? I have a set sitting here waiting to be installed but cant seem to find what ARP studs to buy to make them work with the hubs.

I noticed that the front and rear ones are different.

Thanks!

The fronts should be the same as s14 5 lug fronts.

The rears are the same as s13/s14.
