I'm just curious why it seems like 1963 K20's seem almost non existent? The reason I ask is because as a child my dad had one and I remember it to be one tough and capable 4x4 with awesome clearance, 17" split rims, and the rearside of the underside of the cab had these weird hooks that somehow helped with suspension travel. It almost looked like military grade. I guess they must've not made many because I can't say I've so much as seen such a truck anywhere!
