From what I can tell on my '51 Chevy, the gauge faces were the same color as the interior. I bought a rebuilt Speedo from Jim Carter and they used their interior color on it, which is slightly darker than what was on my dash originally. When I repainted the interior, I bought their paint and had it lightened to match more closely with the original color on some of the concealed parts. The speedo is slightly darker than the original gauge face. I would suggest that the gauge faces would be the same color as the interior on the GMC, whatever that might be.

If you're smart enough to take it apart, you darn well better be smart enough to put it back together.
