A-body Bucket seat frames 74-6 (?)

Guys, I have a pair of bucket seat frames and original foams for sale for a A-body. They were a little too wide for my 71 seat backs, so I think they are 74 and later. Not sure. Pics of foam attached so you can possible identify. The original foam is on the left and the repro foam for a 71 is on the right. $200 for the pair. Can have delivered to Carlisle or Nats. I'm in the Atlanta, GA area. PM me with questions.
