The early 150's have the same seat bottom's as the 120/140's. I believe the very early 150's have the same seat back as well. At some point they changed the design of seat back recline latch. Depending on what design you are looking for, I may have a stripped set of seats available. All of the fabric has been removed from them. Can you post a picture of the seat back bracket that is mounted on your rear door post?
