No, they do not. You need to re-read this thread. Some of the guys on here, like Crackedback, know a thing or two. "If I must" I will go out and spend an hour in the shed digging up at least enough distributors to prove that point
Note that the two distributors shown above have the rotor and the tang offset by 15 degrees. I also measured an old points distributor I had lying around ---- 15 degree offset too.
