Reproduction of the original in dash tachometer designed for use on 1970 Chevelle SS and Monte Carlo models. If your vehicle was originally equipped with a 396 (402)/375hp (L78), 396(402)/375hp (L89) or a 454/450hp (LS6) engine, this tachometer is correct. Each tachometer is manufactured to factory specifications and features correctly silkscreened lettering and numbers in the factory font for complete originality. Tachometers are pre-calibrated, tested and ready to install.
