As long as your old distributor is ok, the tabs that the cap screw into are good and not broken, then there would be no point in buying another stock distributor. In my case I had a more aggresive cam in and wanted the option to get a gear that was stronger later if this one wore out so soon again. The only way to get a gear made of a different material is to replace the distributor with one that uses the more common gear size. For you I would say to either replace just the gear or get the Accel distributor. Leaning more toward just replacing the gear assuming your old distributor is ok.
To post pics you'll have to post them in a photo sharing website like imageshack or photobucket. After you register there, free, you upload photos or movies to their website. Then get code for posting in forums from there and post the code.
You'll be able to compare a new gear to your old one to see how worn down it is. If you look at mine, the new one has flat tops on all of the teeth, and the old one wore all of that material down to a sharp edge at the top of the teeth. All of this equated to a lot of play in the distributor with the old gear. I have next to no play with the new gear.
