f650 cab swap..

[e dog]

Hey guys,
Just bought a single cab f650. Wondering if any one has done a f450/f550 crew cab swap on a f650 frame?

I am sure there is some factory stuff too, but on a medium duty a cab swap like that would be much simpler than it is on a light duty like a 250 or 350 as the frame is straight on a medium, the light duty frame actually dips down to go under the cab from the rear axle. Just need to add the rear support for the cab and go.
