What size lug nuts?

Thanks guys, yes drum brakes, they are rt hand threads, i got tired of tire shop kids stripping my lugs on my mopars, "sumthing is wrong with your lugs, they wont come off, i tried a chisel, and they still wont turn" "Um yeah, its a chrysler, get a old guy to take the rest of them off", so i always replace them now with rt handers, never has a A body before though, didnt know if they were the same.
