Just to close out the history and the thread, here's the 100% true story!
At either the 2nd or 3rd Shasta meet (I missed the first), I think 1988 I met the mysterious "man from the Napa Valley" who had a beautiful 2000 sporting a match box EI distributor that HE had made himself. I was quite intrigued and he told me in general what to do to make one, but I'm not writing things down etc... we're just chatting, but later I'm thinking "I'll talk to my new friend Bill about this." I had already experimented with MSD spark boxes for my previous 620 PU so I was interested in more spark for the Roadster. So when I got back I talked to Bill and before long we went out to the wrecking yard looking for 4 cylinder Datsun distributors that matched up... they were cheap. Brought them back to Bill's garage and before long he had a prototype. I think I already had a MSD Blaster coil, so we figured out how to wire it up. In fact, once we got it working I was comparing how much hotter the spark was by holding the wire away from the cap while Bill reved the car and it shocked me so bad I couldn't let go of it... with Bill laughing his ass off at me!

So after that we kept that one on my car, Bill made a few (several?) others, I think he started doing some with Les C, then I later heard that someone was doing a kit. But obviously I was not in touch with the Roadster community at that time like we are now so I don't know anything more. I know Gary Boone made them because when my original prototype finally died I reached out to him for a new one which I then ran for years.
So, that's the solved Mystery of the Datsun Roadster EI Distributor... if anyone "cares!"
