Ok I got a 77 GM K20 8 lug D44 front and a 79 Ford F250 FFD60 rear I got new lug studs for the front and put them in. I want to have the same lug studs/lug nuts front and rear. I also need longer ones because I am gonna have rear discs. Is there a site that has the sizes of vehicles studs and the knurl to see if they are the same?
