Interesting find. Your right on the distributor base, finding one in usable condition will be almost impossible. A few of us on here have made our own distributor bases, and there is a source here that reproduces them. There is a lot good information and knowledgeable nice folks, on this site.
Take a look in my thread, this is what I did. http://www.1948plymouth.info/28Q29U/index.php?topic=811.0
Also more discussion about the bases here http://www.1948plymouth.info/28Q29U/index.php?topic=966.0
Good luck and welcome
