This is a new Datsun (Nissan) pitman arm.   It is an OEM NOS, not an aftermarket replacement.  The part number is 48502-U0100.  It is unused and has been on my warehouse shelf since it was purchased from Datsun. The actual listing is shown in one of the photographs. The photo is the actual item you are buying.

It fits 1968-1973 Datsun 510

 The part number may have been later superseded to fit other models, but this is the only correct application in the original listings.
