Inasmuch as the probable new distributor was to be a dealer install, I
assumed that you were warning that the 10V MC dist might be inadverently
substituted for the broken 3B dist, which I stated as being an
impossibility.  The substitute of the 7A dist being the only physical and
functional possibility.
