Yes you have to change the oil pump to accomodate either the pin or star
drive.
There are no advantages to either that I know of.
I believe the reason for 2 drives was the 2 different manufacturers of
oil pumps used by BMC over the years.
The star drive being the later type may be "new and improved" then again
maybe it was changed because it was cheaper to make. Most 1275s useds
the star drive as original.
