A good auto electric shop can make the Delco 10-S into a "self energizing" ONE WIRE alternator. Single wire goes from alternator to ammeter to battery terminal on the starter switch. They can also wire them for 6, 8, or 24 volts and POS or NEG ground.
Hardest part is building a new mounting bracket. I paid a lot for a "universal" bracket that looked like is was made from an Erector set. (Only the old guys will know what that is.) Use a 4 inch light weight angle iron. Drill to match the old bracket to block bolt holes. Slotted bolt holes will allow you to adjust it so the fanbelt pulleys line up. Weld or bolt upright lugs for the alternator mounting bolt. You may want to trim away some of the main angle iron before final installation for looks. Belt adjuster may work without much modification. Save the old generator pulley that fits the WIDE belt. You can also reuse an M-37 pulley by chucking it in a metal lathe (The auto electric shop probably has one) and machining the "snout" on the back of the pulley so it is very short. No rocket science here. It should take less than an hour to fabricate and install. Before you do the final installation, use it as a model and make one more - for the next power wagon you buy.
