The mount from the Dude can be found here

His company is called TD racing (I assume The dude Racing). He makes VERY high quality parts, but they are expensive and since you are in Germany there will be extra costs. In my opinion his mount, although very good, is not worth the money compared to the Losi single speed hub conversion (LOSB3408), which only runs 20 bucks. Also this may be more readily available for you in Germany. IMO the losi hub functions just as good as the Dude's, and it costs a lot less. It doesn't have nearly the bling factor as the Dude's though, so it's all about what your looking for.

Also, dezertracer760, if he is running muggy shocks (and muggy shock towers I assume), then his LST is already Muggified. A Rear shock flip is not really an essential component to a Muggification and is a seperate mod all on it's own (that many people do as a part of their muggifiction).
