Sorry, i don't understand, why not directly play F104? At least F104 ball diff is easier to adjust (not inside the wheel), and have better battery position.
F104 can also use rear tire of F103.

F103 can use F104 shell then.
P.S Part of the F104 shell has to be cut away otherwise it rubs against the rear tires
