Source for dizzy gear?

I’m looking for a “reverse rotation” drive gear for a new Pertronix distributer for my
(now) 1974 Ford 302 V-8.
Engine is not original to the boat.
It is a Ford "302" producing 220 hp. or more (“351” heads.)
It is a "Right Hand" (reverse) turning engine (viewed from rear.)
It is a Ford "small block" marinized with components from an engine originally built by Crusader (Parent company was Thermo Electron Marine Engines -- Thermo Electron sold its Crusader line to Pleasurecraft.)
The cam is new, right-hand rotation.
We really don't know who built the “original” engine -- possibly someone other than Crusader (now Pleasurecraft Marine or "PCM”.)

I’ve lost the paperwork on my purchase of the distributor. :-)
I’ve disposed of the “original” distributor. : -(
I bought this one from someone other than Pertronix and was told it was for a “reverse” engine. It is not.
Pertronix does not make the gear I need. The fellow on their “tech line” could not give me a source for the gear.

Any ideas as to where I can find one?

I don't see one on ebay currently.

I've talked to Summit. Nothing there. Yes, I regret dumping the old one. Local "old-timer" thinks there may be a local source. Should know soon.

Thanks, we'll solve it. Have oil in it and all the wires in harness, except for dizzy. Zero here this A.M., so waiting for a break to launch & test run anyway. We've run the oil pump, as you can see . . .

No, Bud Eiler.

Great option and I agree very basic on the lathe. The only challenge may be positioning the new gear vertically on the shaft. Measure the original but, even if off slightly it won't matter with straight cut gears.

Duane,
If the new gear requires machining (or the shaft), then chances are high that the cross drilled holes in the gear and shaft aren't in the correct place.
Grant,
Take a few measurements!

Just wondering how accurate your calipers are.

The typical early Ford 302 distributor had a shaft diameter of 0.467 inches where the gear mounts and people like Mallory, Prestolite etc. made their shafts the same diameter although the hole location for the pin varied. Maybe Pertronix decided to be a little different, or your measurement needs double checking.

Do a search for Sierra 18-26823. It's a 302 RR gear with a .467 inch inner diameter. It's a replacement for a Mallory gear. Ebasic has that one listed.

Whatever you do, you need a cast iron gear or you'll have issues with wear of the camshaft or gear.

Thanks for all responses, opinions & advice.
The measurement I posted of lower shaft is WRONG!
Correct diameter is .449
Yes, we will grease before final assembly. (Already done that once.)
And the ZDDP has been added.

do a search for the 2015 pertronix catalog and scroll down to page 40 "Billet distributor Dimensions" and you'll see the ID listed for their drive gear on their 302. distributor

It's .467 inches, wrong direction of course since you say they don'r sell a RR, but get the Sierra gear I mentioned a couple posts ago (18-26823) and the worst you would have to do is drill a new hole for the pin if it's at a different height..

Forgot to mention, I did look at Sierra gear. $90? That would go a long way towards another distributor:

why is your cam going opposite your crank

So you have a LH cam but need a RH dist gear? Is the cam gear RH? I am hella confused

My sketch is a view from the rear of the engine, therefore "reverse" or "right-hand" rotation.

Duane, do you think this is it?
