Jim,

        All Olds/Buick 215 distributors are physically interchangeable, but
there are many different original Delco-Remy part numbers--presumably due
to different details of centrifugal weights, springs, vacuum advance units,
etc.  If you need it, I can come up with a list of original numbers and
their applications.

        I don't know about crankshaft pulleys but the following dimensions
may be of use to determine if you have the correct pump.  My measurements
show a distance from gasket surface to front face of fan/pulley flange of
about 4 1/4 inches for a stock 215 pump, and about 3 3/8 inches for a Buick
300 pump.  Do not know about V6 pumps or pulleys.

Cheers,

Dave K.
