forgive me for asking as I am sure this has been asked only half a million times but I have a '71 cab on what I think is an older 6 lug frame so if I go by the cab which I think is wrong cause it puts me on the 5 lug wheels then the lug size is 1/2-20 but if I go by the 6 lug frame ie actual wheels than the size is 7/16-20 does that sound right (essentially I got AMAZON more confused than a blind goat on astro turf as they are recommending M14x1.5 which is metric, no?)
