Correct Ballast resistor

The top one visually looks correct for a factory points system circa 1967.
But since you are changing ignition systems, the functional requirement is for the resistance to match the coil and ECU. You'll have to get that from the coil and ECU manufacturer. Been some recent discussion about this, shouldn't be too hard to find the info for which ever ones you're looking at. If its an older MP system, there's a page in the Ignition Bulletin for the different Direct Connection boxes etc.

Later Chrysler ECUs use single ballasts.
Early Chrysler ECUs used dual resistor with one dedicated to controlling ECU current as explained on this page
