1978 Sierra Grande seat pics needed

[evl]

I want to have the seat redone in my 78 gmc sierra grande desert fox, and I want it as close to original as possible. Hopefully someone has some pics of an original vinyl seat they can share, from a 78 truck, and tell me what color/ material needs to be tracked down.
The truck currently has a non-folding bench that was recovered, and I doubt it is original to the truck. What years were the non folding seats available in the trucks?

I know that my Dad’s ‘77 Custom Deluxe C10 has a factory non-folding bench seat. I would assume the folding seats were an option.

77 Silverado = factory folding seat.
OP I’d suggest GM Heritage archive. You can look at all the Chevy brochures and each model year has pics of interior options.
