larger alternator

My Mini has the Lucas 16ACR alternator (Same as on a Spridget, 34A) in it and
with the addition of a lot of lamps it can't keep up.  Lucas 11AC seems to be
the same size, with 43A output.

I know alternator swaps have been discussed, but the archives don't seem to
have anything on outputs of various transplantable models.  Does anyone have
any specifics?

TIA
