The colour is called Prairie Bronze. Had the car repainted back in 1999. Looks a bit worst for wear when you look close.
The bench you are talking about, is it the back seat? Or does your car have a full front seat instead of bucket seats? I’ve never seen that before.
And yes, this site is pretty much dead.
I found one site that says it has a reupholstery kit for front seat bench. Not sure if it will be what you want.
