I have 2 np205 cases. One is out of an '80 one ton and in really good shape. The other is out of a '75 3/4 ton and is pretty much worn out. Of course, the '80 case has a slip yoke. And the front yoke is a plate looking setup instead of a yoke. I am assuming that I can take the fixed yoke rear and the front yoke off of the '75 case and they should bolt right up to the '80 case. Am I correct before I start tearing into things? Or should I just look at rebuilding the '75 with parts from the '80?
