I think the wires fit into a hole (snug fit or sealed)
and can be pulled out. I could be WRONG so look over
carefully...if wire is molded into coil you may have
to cut wire and solder...The Repco Phelon coils I
have seen are the plug in type...the center of the
end of the hole has a spike that touches the ignition
wire metal core. A friend strips off a little of the
insulation on replacement and spreads the wire strands about so as to improve chances of metal to
metal contact. Seems like a good idea.
Let us know what you find.
