I actually bought it through a parts place selling on ebay. I can't remember the seller name. Search for parts for the D-Tracker and you'll probably find it. But any Zeta dealer should be able to get it for you. I've bought a bunch of stuff (including Zeta) from Forrest at Wheeling Cycle Supply, and he's been great.

 

Mustang I love the graphics! Not over done like many. Those shots you posted are BOTM material.
The Zeta sprocket guard looks cool, but I wouldn't call it a case saver at all. In the photos, I don't see anything that would be in front of the counter shaft sprocket to fend off a broken chain heading for the engine case. It looks cool and will keep your pant cuff out of the chain but no more.
