| | Head Stud nut/washer size?
Well I thought I ordered the right ones from Arp but they were too big (Arp 300-8323, 7/16" -20 nut, Arp 200-8512 washer).
I looked in my Ebay history and the seller says Speedmaster doesn't sell them individually. I've tried summit and Jegs but they all say the same and won't bother telling me the Arp equivalent.
Does anyone know which nut(1) and washers (2) I need? This is for a '99-04 5.3 head stud kit.
Hoping I can order these from Arp instead of paying another $100 for some Chinese studs...
