Ford retrofitted a lot of cars, and almost all the Lincoln Mk VII had them mounted remotely in the cowl. If you can scope out some of the cars in a local yard for a TFI distibutor with no module mounted on it, you're likley to stumble onto one. It's just a separate heatsink and a M-F extension cable.

Being that the most common failure was complete ignition loss, sometimes recovering when the module cooled down and sometimes not... your stumbling may not be a module heat issue at all.
