I am in the process of rebuilding a distributor it is a 1962 distributor with the 13 degree advance (it had the pin holding an advance weight  shear off and damage the advance weights). Where can you find the advance weights ( they are the kidney shaped ones) and possibly the advance portion itself? I found new shafts at Dennis Carpenter, but cannot locate the rest of the parts. My hope is to rebuild this one to replace the 1957 distributor  I have, as it has 36 degrees of mechanical advance and that does not allow me to put in much initial advance.
