G'day mannick,
Mate I have done two body lift on my D40's in the driveway of my house, and it is quite easy. No issues at all with the auto shifter, handbrake, fuel filler anything. You don't have to touch any of it. A few mods around the engine but nothing serious. I think I had to move an earth wire, trim a couple of inter cooler pipes, and the engine cowling. All that is required in the cab is loosening off your steering, letting it slide on the spline a little and re tighten
It is very straight forward, I think it took me about three hours including modifying the brackets on my rear step.
