Thanks for sharing your design! CD needs more of this.

Some quick comments. Unless you adjust the spacers on the Ballshifter third stage I don't believe there is enough room for #35 chain. Remember you want to have clearance on both sides of the sprocket for the chain.

With the 8wd if you switch your chain routes it will allow you to sneak the outer chains in a little making the shafts shorter and save a little real estate in your bellypan.

It looks really solid. Nice work!
