68 barracuda dash bezel

Nearly every year of dash requires a matching-year dashframe. AFAIK, there are three frames and five years of Rally dashes, the Barracuda having started the parade in 1967. Every year of Rally-dash has a matching glove-box door.
Some had openings for thumb-wheel radios, others were for knobs.
If you call for a 68 dash, then you pretty much need a 68 frame.
Yes, you can install a wrong-year dash into any frame, but they are not bolt-in. After you are done, only a purest can tell.

The First year of the dash-mounted flasher-switch was IIRC, 1970 or maybe 69, I forget, but definitely NOT 68/67.
