Craig, I happen to have a 79' 930 engine apart here and I checked the part number for the alternator.

It is also 911 603 120 04.

Hope this helps.

Also, does anyone know if the later 84' and up alternator will work? And if so, is it an improvement?

I am not sure, but by the picture here on P.P , it looks as if the newer one has a better heat-sink design for the diodes and voltage regulator.
