I have a 1971 cuda 340, 4spd that is an original California car. I am restoring the transmission and in the side cover is a switch that is activated when the car is put into fourth gear. I assume to meet the CA emissions at the time it retarded the timing in 4th gear only. The male lead is broken off of the switch and I'd like to find a replacement. The reference picture is of a unmolested trans in another car. The 70-71 parts book has a picture of it but the referenced part number leads to a two prong backup light switch. Any help in finding the switch is appreciated.
