Randall,
I believe it is possible to make the MGB pulley swap. (god forbid). I am about
to do this as part of my "upgrade" after my radiator merged with my fan.
I will use a harmonic balancer on the crank, the standard width MGB pulley, and
the
standard alternator pulley on the alternator. Will also use an electric puller
fan for the radiator.
I hope it looks and works OK....
