The new chassis isn't as tall as the old one, so it looks like we'll probably need some additional holes in both the chassis and gearbox to mount them securely. Measure twice (or three or four times...) and drill once.

You're also going to have to cut away part of the top and bottom flanges on the inner plate to get the toughbox nanos to fit in this year's chassis. If you place the nano output shaft through the big hole above 3/8" bolt holes you're also lowering the frame by almost 1/2" which may affect your ability to drive over the scoring platform.
