Alternator conversion

Probably, but are you sure you need it? MGAs don't require much power, and the generator can be rebuild for a few dollars in parts. You would also have to convert the car to negative ground if you haven't already.
 
I wrote an article about this for the Wiki; it's under general technical topics. Might help you decide if it's worth it. The two problems with a generator, that I see, are (1) marginal output, especially at low speeds, and especially if you add any extra electrical components, and (2) the mechanical regulators are really lame. The downsides are (1) need for an electronic tachometer, if you don't have one already, (2) it's obviously not original, and (3) if you don't have extra electrical equipment and don't mind putting the battery on an external charger occasionally, it probably isn't necessary.

I don't quite agree there. Generator output is fine for a stock car. I do agree that with additional power-hungry components, either a generator upgrade or alternator conversion is a good idea. As for the regulator, or more correctly "control box", they are very reliable and like other mechanical components in the car will give warning before failure. A car that is rarely driven may benefit from electronic components to avoid corrosion on the mechanical points.

I agree with Steve! There is nothing wrong with a generator that's working properly. As long as your not installing a high power demand after market whatever, it should supply all the cars needs. It ran on the car for 40 years + or -.

Another thought, a car won't run with a dead battery if it has an alternator, <span style="font-weight: bold">but it will with a generator!</span>
