Is this a Blazer rear seat?

[Spf79]

Hi,

Can anyone confirm what this seat is out of? Blazer? Is there a difference in years of of the 69-72 rear seat? I traded some parts for this a few years back and am now getting ready for interior.

Or is this a suburban rear seat, or are they the same?

Sorry if this was covered in a different post. I did a quick search and did not see anything that answered my questions in total.

Thank you!
