There are probally at least 6 different bench seat styles used. Are you looking for a set or just looking for info? Benches were standard equipment in the grandma cars. I have the base straight bench(no split) in my 82 Regal.
I've got a set in dark blue, full bench (no split in middle) with excellent fabric fronts and rears, even matching door panels, etc if you're new new england and wanted to take a trip to pickup
