Yamaha kodiak 400 new front end

My old kodiak 400 (2001) was due for new control arms and ball joints but found out they were not replaceable on that model and had been welded in from factory. A new set being £400 made me try a different thing.

I am now in the process of fitting a Kodiak 400 (2003) front end on it. For e.g: upper and lower control arms, hubs and knuckles. Upper control arms do fit but lower ones do not so I am now partaking in a bit of welding. Anyways I’m curious to know if they use the same frames. The part number is 5GH-21110-01-00. The knuckle pushes out the top of the wheel once on the ground. This may be the wrong knuckle as it’s off a 2007 (supposed to fit). Any help would be appreciated.
