There is a company in Illinois called 'British Wiring Inc.' that carries
that connector. I purchased one from them for about $6.00, IMMS. You would
then have a complete reliable connector. Their phone is 708-481-9050.

My 1969 MGB-GT has an alternator as original equipment. I don't know exactly
when the alternator was introduced, I think quite early 68. However, the
later models were an uprated version to handle greater loads. The diodes in
the alternators are the weak link. The 18ACR is the uprated one introduced
in 1975.
