Here is a pic of the driver and passenger side covers. Oddly they have 2 different types of wire holders?! I am going to change the drivers side to the "w" type if wire holders. The MSD wires fit in those.
I just got back in town from a business trip. I will have some time this weekend to start drawing that and see what I can come up with and 3d print some and see how they fit on mine.
