Looking before, what about underneat the needle on the analogue. There is a bit of room there, not sure on room behind face though.

Hi Guys,
I've decided to ditch the original; tachometer as well, and maybe later,
the fuel guage also.
I've always wanted my fuel guage to read in litres like the odometer test mode.

I've go tto spend a bit of cash on a water pump first, and then I'm right on
the tachometer.
I was thinking of blue for the tach to compliment the red speedo.. what do you think?

Use Nixie tubes
