sometime ago I pulled my transfer case from one of my older 2.8 liter XJ's to use on a new project assumeing that it was a NP207 case. Upon removeing,I subsequently discovered from the oval outside tag that it was a NP208 and so I went back to the Clinton manual for the appropriate diagram .Now after splitting the case + dis-assembly I find that the internal gearing mechnism more closely resembles a NP228 and I go get another diagram-Does anyone know for sure how I can POSITIVELY identify the CORRECT transfer case I have?-.-I would really like to get on with a speedy and timely rebuild and to purchase a transfer case rebuild-kit, but I am currently stumped.I have been advised by a commercial transmission parts vendor to check the front+rear output oil seals and if they are the same the case is a NP228 and if they different it is a NP208. Also I was told though another process of elimination if,... on the same parts to look for code designation like 207 or 207 over the numerals 6207. - At this point in the process this mechnical novice is beginning to seriously think about going over and sticking his head in the proverbial oven-TIA
