They have to be uploaded to the web and linked to the forum.  

The NP203 is a fulltime 4WD case.  
It will have 5 selections: High, Lo, Neutral, High Lock, Low Lock.  
It consist of 4 sections: range box, chain case, differential housing, and output housing. The front 2 sections are cast iron, the back 2 sections are typically aluminum.

The NP205 is a parttime 4WD case.
The transfer case is one piece of cast iron. It has a short bearing retainer/output housing on the back of the case, and aluminum bearing retainer at the front and rear.

The NP208 is a part time 4WD case.
It is easily identified by its complete aluminum case.
