Source for dizzy gear?

I don't see one on ebay currently.

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?
