suburban front bench seat

[forestb]

I'm visiting from the 60-66 section of the Board. I have a bench seat with head rests and no arm rest nor does the back recline forward or backward and the seat belts come out of holes in the seat and it is vinyl. I got them out of a 90's suburban or maybe a GMC but forgot to check what year it was out of. Can anybody help me figure out what year they are from? I need to know so that I can find some new upholstery for them.
