I wanted III so went to a point type Mopar dizzy. No issues, but wish it would fit in the Mopar electronic dizzy cause it is easier to use the FBO plate to limit total advance. Just had to weld the slots to get where I needed. Cat's meow would be if it was available for the original Prestolite DP, then a real authentic look could have been achieved. I do keep the complete point breaker plate in the glove box just in case something fails and can insert a get home fix.
The complete Pertronix dizzy units I have seen pictured on this site have a really crappy mechanical advance set-up that was hokey at best, but I would venture to say " Pure Crap"! They really need to make a few more drop in units that fit the various Mopar dizzy's.
