Father-Son 1974 Duster Project

A box of goodies arrived from Summit today! Floor shifter, spark plugs and wires, fuel pickup and sending unit and after market two post am-fm radio. We also have the heat-ac control and the HEI heat sink bracket that bolts under the distributor on the way... Since I have 2 stock instrument clusters, we are modifying one by installing an oil pressure gauge in place of the oil-brake idiot light and a 2-1/8 tachometer under the water temp gauge in that big open flat space. Brand tbd. What ever is reasonable and matches well. Decided to set the odometer to 32057 on this cluster since that is the mileage on the title even though there was no odometer in the car when we bought it....

I assume the notch goes over the housing frame in the back of the well where the odometer sits....
