I am bring this thread back, my AFS wheels (black Bullitts) have already been shipped and I forgot to purchase the lug nut kit

. Can anyone tell me for sure if I can reuse the stock nuts? If not what type do I need to buy? I wrote to AFS asking for the specs, but they just suggested I purchase theirs.
EDIT: I just checked the AFS website and they recommend an Extended Tip (ET) Lug Centric nut. Can anyone just advise the size for our mustangs.
