This pump is a direct replacement for some 1962-63 Buick, Cadillac, Chevrolet, Oldsmobile and Pontiac cars. All of our pump assemblies are all new direct replacements, we have brackets and reservoirs made to match the original pumps so all you have to do is install the new one in place of your worn out one and not worry about it fitting. Don't forget to check out our new hose sets and top lift cylinders.
