Yes, "upgrading" from a 63 Amp to an 80 Amp wouldn't hurt anything, but he would have to have the correct mounts. Look at the two pics in my previous post ... they mount up differently.
IF he has a 63 Amp (small-frame) alternator, a shop that specializes in electrical rebuilding could overhaul it and install a "Y-wound" stator for that 80+ Amp output.
