I just
added three new links. That Hampton Engineering one looks pretty interesting -- they said they have complete custom 6 gauge instrument packages for 1955, '56 and '57 Chevy cars and 1955 - '66 Chevy trucks ... and better -- "Create your own design using various castings, panels, gauges, LED indicators and finishes provided by Hampton Engineering."
Let me know if there are others to add!
