Right now for the VC work, I'm actually swapping gauges that were 32-bit with ones from the Electra. The gents here updated a lot of stuff off the Electra that was given to me to help get that project up and going for those tankers and I felt it was an acceptable similar enough gauge to swap in and out for the originals. May not be period or airframe correct, but they do at least work. I've popped over to CalClassics a few times over the weeks since starting this project and have yet to get a response from anyone there either in terms of getting the actual airframe correct gauges converted. I think I mentioned it here, that someone there had mentioned they had 90% or so of those 32-bit gauge files transferred to xml ones. But the forums over there are nowhere near as active as here, so I figured the way I'm going at it for right now, will be the way they'll likely come out. As far as the doors go on these, they retain all of the original animations for the doors. So the large cargo door on the 580F and 5800 and the tanker models all swing up and so do the other doors on the opposite side (I think are the baggage doors). 4 doors total on the cargo versions and 3 on the Passenger ones.
I have the "6-pack" working and a few others updated now and some bonus ones included. At least the basics you can now reference including engine RPM, Exhaust temps, GPS was swapped for the non-functional wx radar readout, and a few other things I can't remember offhand currently.
