will these A-arms fit?

[ibriden300ex]

I have a 300ex and the a-arms on it are just way to small. I was thinking of buying some used a-arms off of my buddys 400 ex. But I dont no if they will fit or not.

if u do a search u will finds lots of info on this. the arms will fit but your stock shocks are too soft. u will have to get 400ex shocks and a top shock mount.
