450r a-arms/shocks on 400EX

[Yamaha350x]

I am getting a 400EX soon and I plan on racing with it but I dont want to spend like $1300 on shocks and a-arms. I was wondering if stock 450r a-arms and shocks would fit on a 400EX and if they a-arms would make the 400EX any wider. Let me know...Thanks :macho

they wont work the 450 a arms are wider at the frame mounts
