I had to fabricate new brackets and spacers to allow it to fit.
I wanted to do this in a way that would retain the standard configuration on the engine so that i can use the old alternator as a spare if needed.
I made some spacers to fit the new larger alternator to the original mountings and then mad a extension bracket to move the adjuster out, to allow for the bigger unit.
These spacers and bracket can simply be unbolted and removed to refit the old unit.
Updating the wiring is next.
