Can anyone identify this bucket seat?

Thanks. That is what I find for 71 Plymouth B Bodies. It's very close, but the ones I have have fewer "ribs" on both the seat area and the back. It's definitely the closest I've found.

I just called the guy, and he's at Carlisle. He said he'll look around for some A Body seats for me. He said he pulled them out of a Demon. Someone must have drilled new holes in the floor of the Demon to make these fit.
