The only manufactures use of a bicolored air pressure gauge as described is for air brakes as mentioned. The same stamping for the cluster is used on most of the GM products including frame only package cars and motor homes.
The position on the stamping is used for vacuum gauge, clock, tach, altimiter and I have seen a fuel gauge there but the fule gauge position was taken with a tach and the owner had the skill to make the change.
