new front seats. can u guess what there out of?

They really look like the seats I had in my 1976 Cosworth Vega. Same color, same wrinkles in the sides, same plastic backs (IIRC, been a long time), same back release lever, just different inserts. Mine were all vinyl. Even the part of the seat track that sticks out behind the seat in the last pic looks the same. Of course, I sold that car in 1992 & I wear tri-focal glasses now.
