barracuda rear Seat

1967 and 1969 Barracuda coupe, obviously. But that may be it. The other candidates would be 67-76 Dart and Valiant hardtops. Darts are longer and have a different rear floor pan, so I wouldn't guarantee the rear seat is the same. A Valiant 2dr HT (Scamp) would be the most likely candidate, I suppose.

I looked at the Legendary Interiors catalog, and most of the hardtop back seats seemed to have similar pattern numbers. So it seems possible. But I wouldn't commit money to it without confirmation.
