I grenaded my transfer case at Rausch Creek last year. I have a 2007 Jeep Commander 4.7 Liter QT II and replaced it with a transfer case from a junk yard out of a 2005 Jeep Grand Cherokee 5.7 liter HEMI with QD II. Its been installed for about 1 year and two months now without any issues. So any TC should work as long as it says NV245J from either a 2005-2010 Grand Cherokee or 2006-2010 Commander!
