One Set of Three Great Neck Brand Clutch Head Screwdrivers for 1955/56/57 Chevrolet and GMC vehicles that use this type of fastener.
I bought these new a long time ago for a 1956 Chevrolet 3100 that I had but never used them and they have sitting with my collection of tools since then.
Some minor rust spots on the shanks but only very superficial.
