Ben -- you beat me to it. I was also getting ready to find the other posts and delete them.

I also forgot about the add on part of the kit.

Applepar --- don't buy a whole K-2006 or 2006C. Just buy the K1515 kit. You have all the other parts of the K-2006 in your K2005 kit. That will give you the component that you are missing, but do need.

Regarding signatures ---- at the bottom of my post (and Ben's above) are some blue links. Click on the Amazon link and you'll find the K-1515 kit.
