Vintage rear hard prisoner seats for a diplomat or a Malibu..

[Shawn L]

Hello I picked up a odd find It is a hard prisoner seat for the rear of a patrol car from the early '80s. I placed it in a '88 Caprice and it's definitely not for a b-body car It's about 5-in too narrow on each side I was curious if anyone had any pictures of diplomats or Malibu's of that vintage with a rear hard seat for reference so I can try to figure out what this seat is for.
