OK my 2C I have never ever seen a OEM Mopar distributor with phase issues unless one of these happen.
Reluctor set in wrong rotation, one is CW the other is CCW that is to get the rising edge signal to the trigger the ecu using the same pickup for both, cost saving for Mopar
Dual point MP pickup used in a aluminum housing
slant six pick up used in 8 or vice verses.
Those reluctors out there slotted for the phasing fix compensates for the wrong combinations only, Seriously. Seen the mis match a few dozen times at least,
