Is this the recall wheel?
bumnround, if I recall correctly your car had a shipped date of in late May, like mine, and that isn't an early 67- but it definitely came with the car.
If it ended up on a 67 built in late May, that wouldn't be early in the year and definitely not early in the model year.
The link Dan posted has a report date of May 15, 1968.
Is that the date when the wheel was recalled/discontinued?
If so, then it could have ended up on 68 models.
