tommyleea, the hassle is... the '54 to '56 distributors advance the timing based only on a 0 to 5 inches of vacuum signal from a '54 to '56 carburetor. The '57+ distributors added mechanical advance for primary timing control and the carburetor vacuum signal was changed to 5 to 20 inches of vacuum.
If you change one you need to change both to match.
There is a fix for some/most(?) early carburetors so they'll control the later distributors correctly.
