Are you lucky enough to have acquired or built a project with a RetroSound Radio and you want to update the appearance or install the radio in a different vehicle without purchasing a whole new radio? Here is the solution...Santa Cruz Replacement Face, Knobs, and Buttons allow you to install the Motor4 radio body into a 1988-1994 GM Truck at a fraction of the cost of a new radio unit. They can also be used to replace a damaged, scratched or missing face.
