This is an original, matching pair of Shelby Cal 500 aluminum wheels, also known as drag slots. The size is 15x10 inches, perfect for classic drag racing and muscle car builds. The lug pattern is 5x4.75 inches, a direct fit for many classic Chevy and other GM vehicles like Pontiac, Buick, and Oldsmobile. Both rims are in good working condition with no bends or cracks, although they could use a good polish to shine like new. The attached Goodyear racing tires are very old and need to be replaced immediately.
