Gauges in Chevrolet truck dash panels during the mid through late 1930’s are very similar and are spaced, from each other, almost the same. Even their smaller chrome gauge rings interchange. The 1934-35 gauges are in the middle of the dash and there is no glove box. The 1936-39 instruments are centered above the steering column with the glove box on the right side.
When restoring these rare gauges, waterless decals are now available to help make them look like new. They are available from Jim Carter’s Classic Truck Parts as well as a few other full stocking dealers.
