j/w but do 250r a-arms fit on a 400ex?

[buddy what not]

yuppers im pretty sure the 250 r a-arms do but im not positive

ive always been told they fit on a 250x/300ex and 400 arms do to. but then there this whole deal with the geometry and all this and i dont think it is the same. but dont take that as a positive answer
