250r a-arms on a 400ex?

[FBRacing76]

Hello guys!
I am looking at getting +2 A-arms for my 400ex! I found a nice set on ebay but they are for a 250r! Are 250r +2 a-arms the same as +2 a-arms for 400ex? If you know please let me know!

They can easily be made work. They just need different spacers, and bushings.
