This cluster replacement for a 1982 to 1985 S10, Blazer, Jimmy and Sonoma. It can house a multiple different Holley, Haltech, Tinker Electronics and Fueltech screens. We can even make them to house guages or blanks for custom work. This bolts up like stock and requires no modifications. All of these dashes are modular so the top bueaty plates and bottom mounts plates can be swapped out for different looks and screens. This can even house a Holley 12.3.
