Hi!
I have a 1980 sports coach based on a GM P30 chassis. It has 454 v8, dual rear wheels, front disc/rear drum brakes. what size lug nuts do i need? according to the info i have gathered so far they should be 9/16 18 RH. Im from europe and we have metric size threads here so i have no way to measure the old lug nuts.
thanks in advance!
