Motor mount for a XXL lst2

The best I have found out there is from "The Dude Racing" He really does beautiful machine work and it is a very cleaver design, very similar to the motor mounts in on road card that have a center that rotates for the gear mesh and then locks down.

Here is his website, he just did a run for the LST mounts, the single speed conversion he makes is nice too.
