250R A-arms on a 400ex

[Knips178]

I need to buy some A-arms for my 2000 400ex. I found some +3 lonestar A-arms for a 250r that might work on a 400ex. Anyone know if 250r A-arms work on 400ex's? What other parts are good to look for that can be taken from a 250r?
Thanks

no they will not, 400ex will fit on a 250r however, but you will need to make a small spacer
