being Bob Suzuki's chassis made for a 26D the MacKee's body would not fit over it.
The cut out was the only thing to do for Jairus to pair the 2 elements.
Mind you, the MacKee should've been paired with an anglewinder if we wanted to be period correct. In that case a 16D size motor would've been mandatory and the body would fit perfectly.
But I still resist the idea of having too many anglewinders around my toy room
