Also fits CCKB engines on Simplicity & Allis Chalmers Garden Tractors with spec numbers 2420H, 2440H & 2733J.
Fits some but not all CCKA.

CCKA on Miller Welders with the following Spec numbers:
2052G, 2237G, 2677G, 2748J, 2778J, 3670J, 3718J & 3848J.

If you have an early CCK prior to spec J with a 6V coil, AND it starts with a 12V battery you can use this coil if you REMOVE the resistor from the circuit that supplies power to the + side of the 6V coil.

A voltage dropping resistor is typically mounted next to the 6V coil.

This is the correct replacement for the early automotive style 12V coils with or without the threaded style plug wire towers.
 
Note: This replacement coil does NOT have threaded towers. That style coil is obsolete.
