JAG, your alternators would work fine with this system. It would require 337 field approval, just like all the other installs, but I've yet to hear of anyone being denied the 337, as its a simple and safe upgrade.
EDIT:
There would be additional wiring required for the older airframes like yours. This upgraded system requires each alternator to have its own dedicated voltage regulator. I don't know how the wiring was done by Cessna on a 337A, but you would need independent circuits to each alternator.
I hope this helps. Feel free to PM me anytime.
