I also discovered that the factory Motorcraft alternator and/or external voltage regulator wasn't working. I've had this Summit Racing one-wire GM alternator (PN SUM-811001) mounted in both my M-715 and '68 J2000 pickups and now it was the Comman D'oh's turn to wear it. The GM has the same mount spacing as the Motorcraft alternator, but the upper mounting boss is much wider, so I severed the factory upper mount as shown.
