So I'm going to have to guess this has been answered a million times, I did the search thing but didn't find what I was looking for. I have a 27 roadster with a 31 rear end and 40 ford front hubs and spindles for my juice brakes. After several trips to the local loser auto parts store, I still don't have lug nuts that fit right. What is the size I need to ask for please!!!! Thanks.
Grab a stud or bolt of that size and pitch and take it with you. Found out the other day that the local shop's 1/2-20 bin is filled 12mm x 1.5 nuts.
