This is a new, reproduction Low RPM (5500 redline) Tachometer Assembly. This unit is calibrated to be run by the generator, making it correct for early 1960 Corvettes with 230, 245, and 250 HP engines. Each individual part in this tachometer is either original Delco, or painstakingly reproduced in exact detail by our Company, Corvette Specialties of MD West.
Why waste time and expense on a used part? This is a brand new tachometer.
