This is a new, reproduction Lo RPM (6500 redline) Tachometer Assembly. This unit is calibrated to be run by the generator, making it correct for late 1961 Corvettes with a 230 & 245 HP engine only. Each individual part in this tachometer is either original Delco, or painstakingly reproduced in exact detail by our Company, Corvette Specialties of Maryland.
Why waste time and expense on a used part? If it has not been rebuilt already, you can bet it needs it!
