The radiator shrouds on the 450 are way different. Different shape, different size, the holes won't match to the mounting points and there is an extra set of mounting points on the top of the gas tank under the seat which the 400 doesn't have. You could probably use the front fender. The rear fender won't match up to the mounting points. You're better off buying new aftermarket plastics made for the 400.

The YZ400 should convert to the '03 stuff along the same lines as the 426.
