Now, I didn't come up with this idea by any means. People have been doing this for a long time on other vehicles, and I make no claim to have invented it.

That being said, some people have used the GM module, but I wouldn't. The Ford module is configured to look for a square signal from the distributor, a GM isn't. Of course points put off a square signal, so it's a perfect match. IMHO, this system is better than my modified Packard distributors, as this allows you to use the original distributor in it's original location, with no irreversible modifications done. Just make sure you remove the condenser, as it's now no longer needed!!!!

Pros:
Points last forever, they're now nothing more than a switch to signal the TFI.
Parts are easily available anywhere.
A much hotter spark than what you originally had, as the TFI can handle a hotter coil than the points could.
More accurate spark timing.
You can keep the condenser in the glove box and convert it back instantly if you make harness capable of doing that. This way if the module dies you can always get home on straight points.

Cons:
Has to be 12v.
You now have a Ford part on your car.
