I can't wait to see the Chassis
I've bought another part dismantled D2 with less rusty axle casings than mine, complete rolling chassis, still got the Auto Trans / Tfer and Props, Suspension and Steering. It comes with same wheels as mine, so can be moved around and steered etc. It also has a shell on top, no interior and a few windows missing .........
The idea is I will strip off the shell and keep the good remaining spares, panels etc, then scrap the actual shell, blast the Axles, Chassis etc etc with Oily Waxoyl and cover it for now.
When the time comes for mine to need a Chassis, I will either get the 2200mm rear section and weld into that one, or just go the whole hog and rebuild the axles etc into a complete Galvy like you are getting
Full Galvy is what I'd like to do !! See if funds allow nearer the time
That way the whole swap will go a lot faster when the time comes
