65 Dart Alternator Not Charging

That would be if I kept the newer alternator correct?

Earlier in the thread it was mentioned that I could get a solid state replacement for the earlier alternator. I may be mistaken, are there solid state versions of the older style VR? If so I misunderstood, I could look for one of those solid state older style VR.

Edit: I found a solid state older style voltage regulator here: 100% New 12V Alternator Voltage Regulator FOR Chrysler Dodge Plymouth | eBay

I wasn't able to find a solid state one on summit or other usual sites. This one isn't too much, so I may grab it and see if it'll work.
MOST old style VRs you buy are going to be solid state. As mentioned earlier, LOOK at the bottom. If there is "nothing" there it is solid state internally. If there are two wirewound resistors on the bottom, it is an electro-mechanical style VR

Unless you are "restoration correct" the newer, 70/ later VR is superior, and the 73 ish and later "square back" isolated field units are superior to all the older "round back"
