Mopar solenoid assy as shown. See pictures for description.
I found the part number listed in a 1978 - 1981 Dodge Pick up manual for the 318 motor.
It is listed for 4 carburetor models TQ-9228-S , TQ9269-S , TQ-9270-S and TQ-9271-S I included snips of those entries.
It should be for the Carter 4 Barrel 8314 797E. It has a triangular bolt pattern, and a single wire.
Feel free to make an offer if this is the one you need.
