We have this car at my shop. The owner claims its an original shaker/rear louver car which it appears to be. Unfortunately theres no fender tag and the build sheet is gone unless its behind the dash or in the headliner

It does have the hole punched not drilled in the firewall for the cables and has a 3 speed wiper motor.

If the car is or isnt the owner doesnt seem to care, its his car and hes happy with it. Hes added the gilled fenders and cut out valance and swapped in a 440-6bbl though he says he has the original base for the 383 4bbl at home.

I figured I would share it with everyone knowing that its a car that isnt know to exist.
