You already sais what v spec to get.. Its the Vzb .21 v spec. The only modification you will need it to bevel the purple engine plate with a dremel and use a flat cutting wheel to do so. This allows the front of the crank case of the engine to sit level. If you dont do this it will hit the engine plate and not sit level.
The Mugen MBx5 mount will work. You will either need to drill the holes for the mount or buy the CF towers that already have the holes for the mugen wing.
