What is the stock front wheel stud thread size? Trying to find some that are about 1/2" longer than stock and not sure what the thread size is. Anyone know of any vendor that sells some longer than stock? Order new rims and it appears I have the backspacing slightly off for the tires I have to run on them, 17x8.5" rims with 4.3 backspacing and may need to run a small spacer.
