Might go ahead and try the one you found, see if it will work.

If it doesn't, drill the extra holes.

Goggle McDonald carb and ignition.

Check the volts at the ign side of the coil with the engine stopped and the points closed. Be sure there is 0v showing on the distributor side.

For a 6v coil, it should be around 7 to 9 volts. If it is full 12v, the coil is probably damaged, and the points burned.

Be careful, leave it too long the can will explode!

position of coil makes no difference. read what it says on coil, you have it partially covered with the clamp but it appears to say use with resistor in your photo.

My go to for carburetor parts is McDonald Carb. It would be good to have the carburetor number available.

The coil says "Use External Resistor". Ballast resistors are not all the same. After installing the resistor, ground the distributor terminal and turn the ignition ON. You should read about half of the battery voltage at the excitation terminal of coil. I have run into situations where the ignition resistor dropped too much voltage. If the battery was a little low, the engine would crank, but not start.

I came to this party late but have you changed points. It is almost always the points. Always start with the points.
