what is this bucket seat out of?

[john27pa]

I bought a set of bucket seats awhile ago and I cant find what they came from. I have them in my 74 duster now, but I dont know if they came from a charger, coronet, early a-body, or a Geo Metro lol. The seat rails almost bolted up, but when I went by the factory holes, the driver side seat wouldve been off center with the steering wheel. If I remember right- wouldve been to the left of the steering wheel-closer to the door. With the bottom cushion- for thigh support??- they stick out a little farther than what most bucket seats do-I think. Any help is appreciated.
