Murray is right, all TP's use the same King Air 350 panel, and no VC.
In the "panel" directory of ech plane you'll find a file "panel.cfg", and they will all contain just one line referring to the default FSX King Air 350 panel. It's a shortcut for plane "translators", which has been used for all these planes.
I would not recommend using the FS9 planes "as is" in FSX; there is a lot of tweaking needed in the "aircraft.cfg" file to get them working in the first place, and then to get them handling as they should.
Even with the FSX versions, I still have a little trouble with the SAAB and ATR taxiing at 40kn with idle thrust... That's one of those performance parameters you ccan tweak in "aircraft.cfg"
