I have a 1962 f100 Unibody and my friend has a 1962 f100 4x4. On both of the vehicles right below the window on passenger door the sheet metal interior hinge side is a small chrome tag with nothing on it. Something was glue to it but has slid off long ago in the Eastern Oregon heat. Could someone enlighten me as to what is supposed to be on it or post a picture of it? it's at the same level as the vent control but on the door.
