'69 Mark III - does anyone have OEM part # for distributor?

[BobCT]

And, were they dual point from the factory? Pertronix thinks I might have the wrong module for my car which is currently Pertronix # 1281.

I'm fairly certain my distributor is original to the car. The only thing I see is "Autolite 12127" on the side. Is there a Ford part # as well?

The 1281 should fit almost every Ford V8 from 1958 to the early 70s. They were not dual point. I’ll see if I can find the #, but really, they all take the same point plate and Pertronix unit.

Part number is C8VF-12127-G.

[BobCT]

damn, I thought this might have been the smoking gun. Ok, thanks for checking and part #.

You are running their matching coil? If not, the coil you run needs to be => 1.5 ohms. You might check…

[BobCT]

yes, using their coil.

There's another thing I thought of, which you may want to examine. I just remembered your car has the old point setup, meaning a negative wire (sources I read call it the "primary wire") that goes between the points and the "-" side of the coil. Does the Pertronix system you have require using this wire? If so, you need to examine its condition. I've learned that, over time, this wire will become very brittle; when it does, it tends to break the core. It may not be a full break, but it may be enough to not allow full current to pass through it. Examine that wire, especially at the point it goes through the distributor shell. If it feels very floppy, it's likely broken and in need of replacement. However, I must stress that you cannot replace it with just any piece of wire, like standard copper wire. The metal of the core is not copper, so using any copper wire will cause more ignition problems not far down the road, so to speak.

New negative (or primary) wires can be found on E-Bay; at least that's where I found one. They will not have the molded plug the originals have to seal dirt from getting into the distributor; however, if you can carefully slice the original plug length-wise on one side with a razor, you may be able to transfer that piece from the old wire to the new one.
