what did this rear bench seat come from?

[BlazinC5]

I have had no luck figuring it out. I have had it for 3 years and trying to look up seats on the internet is a cluster of everything but what ya want. Anyhow I believe it is a GM make, possibly from a van or blazer, But I really have no clue, even what years. It is a quick disconect type, but the back does not fold down.



Any idea's ya'll? I was thinking if I could find the floor mounting parts from the vehicle I may use it in my Blazer.
