The wires in that pic look like early style or something the rat rod guys would run.
He has other styles of wire jacket.
I’m not sure what style your year truck had originally, My 50 had the black lacquer type.
I bought the kit classic parts
sold ,
I ran them for about 20 minutes. It was quite a shocking experience. I quickly tossed them and got a set from CARQUEST. They are a gray color wire with boots.
Good Luck
