T-maxx Custom Truggy Chassis

Alright for a diff i plan on using a Hot Bodies Hardened Center Diff 50t
I'm going to cut a piece of left of 1/8" aluminum and the T-maxx tranny case to make a diff mount and top plate. And use the T-maxx Brake setup.
But my question is, which brake hex will fit around the Hotbodies diff output cup?
A or B?

[_paralyzed_]

the answer- C. A hot bodies brake, it will fit in the maxx pads fine.
