It's the grey plastic E-Revo chassis that needs to be modified. There is a small tab of plastic that needs to be dremeled down a bit. It holds the stock diff case in place, but the Hybrid cases are bigger so some material needs to be removed.

Look on the page in the RCM store: "Slight chassis modification required for ERevo installation." I don't want anyone going and hacking up their RCM diff cases.

Right right right... Sorry I had my words backwards! And in a BAD WAY! I kept saying housing, caseing..etc... I meant you have to modify the Erevo BULKHEAD, not "diff casing/housing" Duh!! You def do not touch the Differential case, PERIOD!!!

Use a blue sharpie or something to color the inside the bulkhead, like Capt Frenulum said, so you know where to take some of the bulkhead away so that it fits. And he's right... just a little is needed. Too much and your bulkhead will be extremely thin and will break.
