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 late 1960 thru early 1961 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 Maryland.
Why waste time and expense on a used part? If it has not been rebuilt already, you can bet it needs it!
