Father-Son 1974 Duster Project

Ok so I just went through this on my 72. The motor part number was a 3 speed....found that out on a site called Rick's Restorations. It matched the interior switch that was a three position knob. New ones on the 3 speed are all over on prices but I just. Got a bench tested one from FABO member Tony whitepunkonnitro. Wires are hard soldered to unit so you need the harness on it. Bulkhead to motor wiring if you don't have it is available at year one for under $40.
