Craigb23,
If you are wanting to use the superdish for 129 only, it doesn't need a kit. Just aim towards the 129 with one of the 2 "regular" LNBs; and use a regular Dish 500 for the other satellites.
If you are wanting to update the superdish into a Dish 1000 (110,119,129), there were some posts early on about modifying it to serve as a Dish 1000+ (110,118fss,119, 129) but it seems the concept fell to the curb.
If you are adventurous, you could graft a Dish 1000 "W" bracket to the superdish arm (keeping the focal length correct) and that would create a large Dish 1000, bigger than the "new and improved" 1000.2.
I believe there are adapters that allow the mouting of a conventional 1-5/8" mount dishes (Dish 500 or Dish 1000) on the superdish post. That would be easier than fabricating your own Superdish 1000.
