Do you actually need an alternator? A good dynamo on a standard car is quite sufficient, even in winter.

Well, the Minor's electrics are pretty limited and don't draw much current; if you struggle in winter with wipers, heater and lights on all at once first check dyno brushes and then perhaps upgrade.

I have to say I never yet charged a battery on a standard Minor because the dynamo wasn't charging it fully.

change to an alternator is very easy and well worth while,if you do a lot of short runs and winter driving,and want piece of mind all year round,second thing I did after radials,however I do have a heated rear window plus radio and like to run on sidelights.
one year and no problems ,ya pays ya money and takes ya choice ,good luck :D

First move would be to change to -ve earth........ and by all means get an alternator (or two) in stock by roaming the local scrappies...........
