68 dart alt upgrade also a ?? on headlights

i planned on the wiring upgrade also.. i do plan on adding an electric fan, a/c better headlights and radio.. pwr brakes and sterring and maybe EFI. but if i do the upgrade id like and alt that would bolt right in.. I am not sure if the mopar alt (75 amp) would be enough, so I would like a 90 amp..

is there anyone that makes a 90 amp in a mopar case?
