A suitable "block" ballast resistor should be available at any auto parts
store. If they need "make, model, year", tell them it's for a 1964 Dodge
Dart 225 slant 6. Or TRF carries them under P/N 134176A. They show
application as "S15G13" so I'd guess you're right about your later car
having resistor wire instead of the discrete resistor.
The ballast resistance should be around 1.5 ohms. I believe proper units
will have a fairly high positive temperature coefficient of resistance so
the current goes down as the resistor gets hot.
For short-term testing (less than 100 miles), you can just run without a
ballast. I've limped home that way several times over the years.
