I'm glad to hear the oil pressure gauge checked out okay.

Yes, check with AAW to be sure, but I don't think their Classic Update wiring (like the one you purchased) support the factory ammeters.

The replacement ammeter from Classic Parts you linked to appears to use an updated style of meter movement / coil assembly. However, it would still function the same as the original and require the same wiring configuration. So I'd recommend holding off on buying that until you hear back from AAW. And if you do have to change over to a voltmeter, check with fellow member TBONE1964 ... I know he offers voltmeters to retrofit into the 67-72 gauge clusters and I believe he makes them for 64-66 too.
