I did some more measuring last night and the Mallory fits in up to the second "lip" and the stock distributor fits in so that the groves in the shaft are just below the surface. What are those grooves for? WHy is there a hole there? Oiling? ANd for my final stupid question, how does a vacuum advance work? It looks like it just clamps on to the distributor shaft. If that was the case, couldn't I just clamp it onto the Mallory? John Meredith (above) says I can have the Mallory machined to accept the VA, but I don't see anything on the stock shaft that would indicate anything would need to be machined.
Thanks,
joe
