I was going to replace a couple of wheel studs on front of car today and I went to store and picked up what I thought was right stud but the were a little to small and the thread was 7/16" x 20 they were arp I used a caliper measured the old one at the knurl was .492" and the new one measured .482" does anyone have maybe a arp part number to what will have correct size knurl
