This is the seat correct material from
1963. I believe 62 was the same but I have no documented proof. The Vinyl is called Hair Cell, it is a series of small dots like a shaved head. The seat frame and foam is original to the truck. I was lucky enough to find the end of a roll of the original fabric to have the seat redone. Not a great shot but to give you an idea of what it should look like from the factory
