1965 Dodge Dart Charger

Ulf, the last lug nut you posted is not correct (with the size stamped in it) that is way too new. The picture you took that I attached is the one I would guess to be the correct one, the head looks like other Cragar lugs from that period. But the question I have is is that washer in the picture part of the lug or is it a loose washer? The washer should be seperate.
