More gauge work:
With only three holes in the cluster I had limited options for adding a tach. I also HAD to have speedo, fuel level, H2O temp, and oil pressure. Five gauges in three holes means multi-gauges or cutting additional holes (no).
Since the OG cluster came with a multi, but only used one of three slots I went with that style. It had oil, water, and amps. I needed oil, water, and fuel and happend to get lucky enough to find one on ebay from a MG, Morris, Austin, AC...
The only visible difference from the Sunbeam/Hillman style was the center "button" and needle color. That was easily fixed:
This looks much worse than it is because of the flash.
Now the center cluster hole is freed up for a 52mm tach
Here's what's on the way for that. I'll try to use the Minx bezel and needle. Maybe re-silkscreen too:
