Should work.

You'll need a #10 or larger wire running from the alternator output post to the wire on the "bat" connection on the voltage regulator. Assuming it is a one wire alternator that should be all the wiring you need. Check back with us if it is a 3 wire alternator.

You will need to modify your generator mount to accept the much narrower mounting arrangement on the alternator. You may be able to do that with just spacers and/or washers to position the alternator fore and aft. You will likely need to provide a different adjustment bracket as well.

Make sure you get an alternator with a pulley that matches your belt. The two pictures you posted use different sizes of belts.
