because the actual diff gear is the same and all.
I'm thinking it could only be incompatible is if the outdrive diameter is different and or the outdrives are too long - which case it could be cut down...
Yes the 201 and the FF03 share the same size diff cups.
Tamiya also makes the Hop Up Part # 54233 which are aluminum and come with the plastic dog bone "blades" and plastic diff nut carrier.
