Interesting. I was not aware of this option, but am not surprised either.
Any idea when GMC and Chevy ceased to be different, ie. where GMC was an
upgrade of Chevy? All I know, is that now, the only difference I can find
between a GMC Yukon or Suburban, and a Chevy Tahoe or Suburban, is the
badges, and the price.

> For certain AD models, GMC offered electric temperature gauges with an
electric sending unit that looks very similar to the 12V unit offered in the
later 50s (except it's a treaded top instead of a clip top). Because of
it's uniqueness, I like the electric gauge over the capillary setup you
describe. However, looks like lack of information on the electric gauge may
be the downfall.
