What years had optional Houndstooth interior

[Boones]

I could use some info on what years Chevys came with Houndstooth fabric inserts on the bench seat. I found an orange 71 Cheyenne with orange houndstooth inserts.. Is this a factory option. should i have been black & white houndstooth?

Any pics of what the seat/ insert is supposed to look like would be greatly appreciated

Thanks
