The one thing that has always driven me nuts is when you have metric studs on the front with the C6 hubs & 1/2-20 studs on the rear for 9 inch Ford.. Sent these out to the machine shop to re-drill for srcew in studs.. Now I can run 3 inch studs on all four corners with Trans Am open lug nuts..
Concentric within .001 & we build a fixture for us to convert the rest of them here @ the shop..
