, and then swap the HEP wiring.
I also drill a recess where the distributor base screw hole is so that the HEP key fits in it when flipped 180 degrees so there is no need to modify the actual HEP.
The wiring can be changed in the alternator/temperature sensor/AC/HEP engine harness by simply swapping the signal wires in the connector.
Feel free to reply or PM me if I can help.
Note that not all of the distributors have the pin in the same place so you can't base the shutter position on it. You have to do it relative to notch for the rotor on the shaft not the pin that holds the plastic to the shaft.
It should look like this:
Notice that the "arrow" points to the side of the windowed shutter.
If you use screws then make sure they are low profile. I chose peel rivets so that they would be as tight to the shutter wheel as possible. I also don't drill the originals I just grind the tops off so that they also hold the wheel tight. BTW be careful because if you drop the shaft it will probably break the plastic.
The distributor mods are based on Dave Bohrer's instructions. My adapter is my own design because his used very non standard thicknesses on the components which would have made it more expensive to machine.
No big secrets here as it was Dave's idea I am just trying to enable people.
