G body seat identification help

[oldss72]

I am trying to identify some seats that came with a project I had a long time ago.

I was looking at photos and these look like seats from a monte carlo or other G body, but I am not sure. They are a very nice burgundy velour seat with vinyl backs on the front seats and bottom of the bench seats. There are chrome ashtrays on the back of the front seats.The Foam is in excellent condition and they look like they have never been installed. I could not find any part number on the pieces. The front bench is 60/40 split.

Thanks !
