    I now have a NP 203(?), thats what the blue label says on the side, and a NP 205. What is the difference? I know both are big, heavy, and made of metal. Thats where the knowledge stops.

    The 203 is a fulltime chain driven case, the 205 is a gear driven two speed part time case. The 205 is definately the better of the two.

    Actully your case is tougher than anything but the 205. Let me put it this way. They can handle a couple hundered thousand miles without failure running full time. I wouldn't worry about that case till it fails. It's near impossible to find a 205 that will bolt right up to a TH350 tranny without spending a couple hundred bucks on adaptors on top of the $300 or more that any junk yard that knows how rare one is would want. I hit the local yard today that I deal with a good bit see if he had anything come in that I would be interested in (he did have a 14 with a detroit in and 4.10's :). Asked if they had any in. His comment was wish I had 50 cause I could take the rest of the year off if I did. He did have a 465 and 205 that he would let me have for $400 for everything including the linkages :) I figure I can hagle him down a few bucks.
