I happened to put together a very nice B distributor complete, and found the B condensers available from Tam's Model A. But after discussing the expectations versus compatibility with others, decided to keep the stock set up for now. The main reason is you have more degrees manually on an A distributor than a B. I think you give up around 14 degree movement with a B distributor, which means to run it at full advance you give up full retarded, which would negate hand cranking. I have spoken with the Nu-Rex representative and apparently that centrifugal system gives about 30 degrees movement, so when I upgrade again that will be my choice.
