There may be more different parts (I understand the diffs are a new design) but I don't imagine they make a difference to setup options. You might need a pair of new belts as well. This is my intention anyway. And my idea is to go with the Yokomo motor mount, old (2014) or new, we'll see.
The bulkheads are wider apart than the 418. They are back in line with the suspension mount holes as they were with the 416. You can see this in the pics of the bottom of the chassis. Since they are wider they will affect the camber link locations on the bulkhead caps. So maybe they changed those too? I dunno but the bulkheads and caps look different.
