Here's the reason I'm asking. My '68 had a tag much like yours. How much I don't know because I don't have that truck anymore. Mine was aluminum, original paint on the backside, riveted in where the passenger side defroster vent is (I notice yours has the rivet holes). The front had a Ford logo, my vin, and looked to be very original to me. But who knows. I know of one other '68 with this tag and now you make three. Maybe someday we'll know the story.
