Electrical ??

If you can get the brushes, diodes, rectifiers and bearings, rebuilding alternators is pretty easy. The hard part will be finding the parts. No one seems to sell them anymore. Plus, a rebuilt is pretty cheap these days. My brother probably has a half dozen laying around his garage if you want a used one. Check the output voltage first, though. These cars are notorious for dimming at idle. That's why I went to relay systems for most of my lights.
