The Olds 442 first hit the market in 1964 to compete with the fast growing popular Pontiac GTO. Originally stood for 4 barrel carburetor, 4 speed transmission, and dual exhaust. It's said any cutlass or f85 could add this high performance package for $285.00. Archives show only (10) 4 door cars were ordered with the 442 package.I've included pictures of some of my other very well crafted keychains.
