HRD> The radio on the headliner is a cool idea! I personally never thought of that. I drove big rigs for years and most of all them had the radio on the headliner. I don't know why I havent't thought of that. I've been trying to find a solution for mounting a 5" speedo along with a 5" tach and still having a place for the rest of the gauges. Putting the radio up high certainly opens up some possibilities.
