I used Autometer Phantom Gauges 5 inch Tach and Speedo, 2 5/8 inch for Fuel and Oil Pressure.
My Water Temp, Air Fuel Ratio and Voltmeter gauges are digital and will be located in central console.
All modification will need only 1/2"x 1/32" aluminium bar to make brackets from and some screws.

Modification is reversible to stock look and  can be done any time if you save the stock gauges.
I will post the part numbers for the gauges, but you can use any 5" and 2 5/8" to build it
