HEI distributor on 400 big block in 1974 Dodge Dart Sport

This should be most of the more common stock mounting coils. You can go to an external coil as well, however then you lose the point of HEI which is to have everything self contained in one unit for a clean installation.

Feel free to post any other findings, just trying to keep a descent record for anyone who is thinking of going this route.
Hopefully this will prove to be a reliable and powerful option for people looking for an aftermarket ignition set-up that do not have the money to spend on an digital ignition set-up like the MSD Pro-billet distributor ($350), MSD digital 6+ box ($350) & MSD HVC coil ($150)...
