450R rear end on 400ex?

[rideahonda]

Has anyone put a 450r rear end on a 400ex?
I've heard that the 450 swingarm will bolt up to the 400, is this true?
Will I need a 400 chain or a 450 chain?
Will brakeline be long enough?

I got a whole 450 rear end and 2 month old front and rear GT Thunders that came off a 450, all for $600. Deal?

do I need to use the swingarm or can I just bolt up the shock to my 400 swingarm? the shock is revalved and resprung. will it still be beneficial? if so, can I just bolt it up to my stock 400 linkage or should I use the 450 GT link that came with the 450 shock?

I've done a search on the 450 shock on the 400 and have only found that the stock 450 shock is not beneficial. But this shock isnt a stock shock, its already resprung and revalved.

i would give it a try but use the 450 link with it. steve
