New Era had some for a nitro stampede. The nitro sport and nitro rustler had carbon fiber chassis and incredible goodies that are long gone. 😪🥺
For the electric 2wd, flm, Hot Racing, and Integy have one, buy I'd look into Integy before buying one.
The diff housing will not. Electric is 48p, nitro 32p. The internal planetary diff gears will. I have swapped them before. Some drills have the same gears also. Some drills a a tad too long.
The aftermarket aluminum spool should fit also.
