3.9 Odd fire vs Even Fire

You're going to have to replicate the diso'd reluctor, or else you're going to have one of two things, a shitty running 3.9 or a blown up 3.9. Even fire isn't an option there, and I
see no way to make any existing reluctor into what You need. Same for points. Sorry. Why do You want to do this, if I may inquire?

I have the extra engine sitting around and an 87 Dakota with the same engine that I'd like to "retro" to make tuning possible. As it is, it runs but the analog computer on the fender is meh, at best.

If I had a picture/drawing of the old MP reluctor I could maybe make something.
