My 73 has a large Hornet cap that fits in the middle of the rear panel, not behind the plate (4door sedan).
Wow -- my '73 Hornet (two doors) has the flip-down plate. I recall checking the VIN for "3". I'll post the VIN later.

Quoting Tom Jennings <tomj@xxxxxxx>:
73-up has the flip-down license plate -- is that true for all Hornet/Concord through the end of AMC time?
With a one-year app I guess a locking cap with bug is unlikely.
