It is the D.U.I., purchased approximately June of 2007 from Classic Inlines, and installed at the beginning of August with the remanufactured 200 from S&S.
Replacing that gear will help you for a short time, but replacing junk with junk is a short turn deal.
As of right now the AC Delco F719 gear might be your only temporary help. That is the best of the worst.
The sad thing is the camshaft drive gear is also probably scored.
When you install a new gear, make sure you lubricate it well with camshaft breakin lube & use an oil with ZDDP in it & or use one of the additives available from the camshaft manufacturers.
If anyone is lucky enough to have no wear on your gears just leave be, you are one of the spared ones. Bill
This what MSD has done to stop the gear wear problem, however nothing is availabe for the small six cylinder engine. This link shows what can be done to stop the wear.

guys - here is a link to a detail page on the height and correct placement of the dist gear on the shaft - obviously wont cure soft gears - but setting to specs wont hurt:

Guys,
I've been reading about the cam gear problem & if we can get the specs (a blueprint would be helpful!) then I believe that we can make the cam gears. I am a machinist & have access to a full machine shop. We could use 17-4 Stainless steel which gets 42-44 RC with a 1 hour heat treat @ 900deg F. If someone can get a blueprint then I'll attempt to make a few. I even know some places to get low friction hard chrome coating done relatively inexpensively. Based on what I've seen, once it is set up & running, it shouldn't be more than a half hour in one.
The gaunlet has been thrown down...

It looks like I'll be able to borrow my dad's Bronco for a driver (he can't drive anymore because of his health) until I can get things sorted out with the gear. I don't want t o rush and get a 'temporary' fix and have to change gears at every oil change. 
Just curious what kind of a hardness the original distributor gear had from the factory..

According to simon's tests, 24 or so RC. More info in this thread:

Heres an excellent read that Mike (AzCoupe) spent some time researching and putting together a couple of months ago that addresses the distro gear problem.

The bottom line here is a dizzy gear which is not heat treated.
With less tooth contact than the original ford drive gear width, the driven gear has to be close to 40-45 RC in hardness to withstand the psi of surface contact on the narrow camshafts available now.
I have spoken with Ray at crow cams & their gear is 45 RC. He said that fixed the wear problem 20 years ago.
Most of the replacement gears in the USA are produced in china, do i need to say anything else. They for the most part produce junk.
Mike's article is very informative, but unless the dizzy gear is over 40 Rc in hardness you will still have a wear problem.
The oil you use must have the proper amount of ZDDP to help prevent scuffing on the dizzy gears & lifters which are a high load area of the older engines. Bill

UPDATE:
Bil, aka 'wsa111' was kind enough to let me buy one of his extra Crow Cams dizzy gears, and I got my car back up and running last Friday afternoon. Just for 'giggles', here's some pics of the old gear.
