Cutting the 1973 Duster insterment gauges question??

You need too keep the voltage regulator if you want the fuel gauge to work, its the little rectangular box sticking out of the back of the board. If your going to move the fuel guage your going to have to solder jumper wires from the circuit board to the guage to go around the tach your adding. Sounds do able to me but it looks like the tach wont cover the holes for the original guages.
