Greg-the most economical way to solve your question is:
1.Ensure your broken coil is good. Get a self tapping screw that conducts well, and screw it into where the original coil broke off.
2.Set a multimeter to the 20 k ohm setting and connect the 2 wires from multimeter to the screw and the earth wire from the coil. If unsure of earth, just use the shorter one.
3 As long as the multimeter gives a reading of about 8 or less k ohms, it should be ok, so you can use it. Hook up some thicker than normal wire to the screw, and tape it up/use heatshrink to strengthen.
4. Purchase an ignition coil. They are readily available online for about 20-30$
4 Install ignition coil in the well that held the points and condenser. Just cut the wire that goes to the breaker points and join to the coil. Bolt the coil to a hole so it earths. Might have to drill one in the stator plate.
5 put your coil back onto E core
Your engine now has electronic ignition.
