Hy Raoul, in order for the fuel gauge to work it must have a sending unit which operates in the same ohms range as the gauge it is designed to work with, I am not aware of the ohms range that Studebaker used, but I would find that out if I were you. The temperature gauge will require a matched sender as well if it is the electric type, if the gauge is a capillary tube type (long tube which runs from the back of the gauge to the engine) then that tube must be intact or it is useless. The speedometer will work if the cable connection is the correct type for the cable you have in your truck. In short I don't know if you will be creating more problems for yourself by trying to adapt Studebaker gauges to a Chevrolet, good luck.
