None of the plastics from an '07 WR or a '06+ YZ are a direct bolt on. You may be able to jury-rig something, but it'll look like an abortion. I put '05 YZ plastics on mine except for the side panels and they all fit perfectly except for the front number plate. It would've worked if I ditched the odometer. I kept it, so I had to fab up some some brackets from aluminum bar stock I had lying around. A couple of 90° brackets and I was good to go. I bought all of mine from various OEM
sources, Zanotti's, Bike Bandit and TT OEM.
