Here's what I did when I wanted to add extra gauges into my dash facia.....
I cheated and bought a carbon fibre one from Thunder Road.
And I installed SoCal Gauges.
So this is what she looks like at the moment. I installed this dash in Janaury last year and so far haven't had a chance to drive her yet to tie in the speedo, but all the rest of the gauges work real fine.
And this is her.....
