A friend made a dashboard for his Tiger out of two sheets of plywood,
laminated together. This was to take care of the stepped holes. The
holes in the backside piece were cut larger to produce the required
steps when the two parts were joined. He had both parts programmed on
a laser cutter at his work, so production was easy.
Consider this: If you aren't into clocks, make the clock hole in your
new panel the same size as a gauge hole, then you can drop in a
standard sized voltmeter, fuel pressure gauge or whatever.
