03 WR450 motor in 250 aluminum frame chassis

I have an 03 wr450 that I'd like to put into an aluminum chassis. The 450 aluminum chassis seem to be much more difficult to find and much more expensive. Has anyone else tried this project? How much modification to the frame is required to make the 450 motor fit?

The dry sump will need an oil reservoir but I believe the Al framed 250F has an external oil bag for the motor so maybe you can look at that to make something work...

Good luck, take pics if you do it:ride:
