does anybody know were to buy or find a factory dash kit all gauges included for a 1979 pickup with the factory tach in it???????? My former Truck had one but the truck was a piece so i sold and bought a new truck and it didn't come with one. kicking myself! the new truck is awsome and that is really the only thing i wish i had off the old one. also how $$$ is it gonna cost me to get one??
