One thing I did find interesting to note is that the 77 gauge clusters (at least the 4x4 ones anyway) do have an "OIL" light at the bottom of the speedometer right next to the 4 wheel drive light. On the spare 77 cluster I checked, it even had a bulb in there and has traces on the printed circuit leading back to the cluster connector (same pin as the oil light on a non-gauge cluster). And if I'm reading the 77 wiring diagram correctly, it looks like it might already be wired up to that unused blue wire/plug behind the engine. Looks like I could add a Tee fitting, pressure switch, plug the wire in, and end up with both a gauge & an oil light.

I was going to say that ,but thought maybe it was just my old age kicking in (not remembering real things...lol). When i had my shop, I worked on tons of the older Chevys and I kinda remember seeing a few with both a mechanical gauge and a light.The sending unit for the light used to be sideways behind the distributor infact, I think my Dads' 73 was one of them.
