Ok here is cheesecakes informative post regarding the current rc monster kit for the rc8
The motor mount fits excellent. the radio tray is where the issue comes in. the radio tray sits to low due to the larger diff and the way the chassis brace mounts. There is a easy fix for it though. For those that have the rc8t kit you have shims that come with it to shim the servos up. instead of using them in between the servo and the radio tray use them on the stand off and the radio tray on the bottom it will raise up the tray. i used 2 large shims on each side to raise it up. it gives it about 4mm of clearance over the center front drive shaft
here are some pictures to help you out
Here are the shims i am talking about
