Alternator plug problems

Hi, everybody! I'm a newbee here, and I just bought my first Wrangler. It's a 93 YJ with the 4.0, 5 sp, and 99k. I bought it knowing that it needed an alternator and battery. I thought, ok no sweat. I've done many of these in my time. But my problem is with the alternator plug. The two large (maybe 6 gauge) wires came off easy enough, but the other two flat spades that are coming out of the black plastic box are giving me the issue. The hardware that connects them to the alternator is completely rusted. To the point that you can't even tell if there's a nut on a threaded stud or what. It looks like two small posts of solid rust. My question is how would any of you resolve this? I definitely don't want to butcher the copper spades, but I feel like I might have to just to be able to remove the alternator. I'm gonna try to attach a pic, but not sure if my laptop will let me. Any help will be greatly appreciated!!!!

Yup there are nuts there,,,,or they used to be nuts. Best thing to do is hammer and chisel the studs off. That what your spades are intact and your new alternator will have them.

Also, is this a voltage regulator / rectifier?? If so, are they the same on all the jeeps? I found one from a late 90's Cherokee in a junk yard. I wouldn't mind cutting the two green wires and one black wire still connected on mine, and just splicing in the new used one. But I don't know if the voltage output will be the same. Something I'd rather not mess around with without being 110% positive it's the same thing.
