'67 Dart - No stop lights, turn signals on but don't flash

Thanks for homing in on the location of the short. I'm off to a car show today in my son's '72 Satellite so I won't get any checking done until later or tomorrow evening - reserve car luckily.
It's interesting to hear that you don't get something for nothing with regard to the one-wire alternator; it does seen like if it can be done then why aren't they all like it...
I will sort out the short and flashers before touching the alt but -
Do you have a part number for the 'correct' alternator? It's a 360ci in a 6-cyl car. It would be a 55A alt?
