The new center pulley doesn't have the belts offset from the spur gear like the 416, they're exactly the same distance, and the spur rides in this tiny little slot in the top deck. It looks f*ing dialed.

Also, this new ball diff is a really nice improvement. It's a chunky monkey, but having the hubs fill the pulley is awesome. It looks like a direct fit in the 416.
