These FR63 caps are missing some of the yellow stickers
Maintain the period-correct look and function of your classic Ford flathead with this genuine Stant FR-63 Oil Filler Cap. This is a vintage New Old Stock (NOS) part, featuring the classic breather design with the correct air scoop often used on early Ford V8 and 6-cylinder engines. It serves as a direct replacement for the original equipment cap, ensuring proper crankcase ventilation and preventing dirt ingress.
This part is designed for the oil filler tube on specific 1941-1953 Ford passenger cars, trucks, and tractors, as well as 1949-1950 Mercury models equipped with L-Head (Flathead) engines.
