On the '67 St. Louis Plymouth B-bodies I've seen, the inspection stamps were in the fender tag itself, not on a separate strip. Would be interesting to know what plant this car came from.
VIN is RP23H75xxxxxx - This seems to be a Los Angeles, CA built Satellite.. so yeah, maybe the inspection tag got left behind or that's maybe how they released them from the assembly line..
Broadcast sheet can still be puzzled together.. or can at least read some of the option codes..
That will a project for another time.
