Default ARP extended Wheels Studs

I'ev been searching for the last half an hour, been on the phone with Summit, and can't seem to get a confirmation on the part# for ARP wheels studsfor a 2001 GS430.

I bought the ones from Ichiba (50mm length) and something is seriously wrong as the damn splines just won't go in... They are too thick for the wheel hub.

Anyone have a solution?

Thanks,

BayArea

I did and found ARP#1007715 for an IS300.

I believe they are the same a our GS300/400/430 but cannot confirm. ARP offered help.
