The New Process 205 was also used extensively in GM, Ford, and Dodge. GM and Dodge used the 205 in some trucks into the early 90's, Ford stopped using the 205 in 1979. The 205 is a part time 4wd 'case, meaning when it's in 2wd the front driveshaft will not receive power. It has 4 stock shift positions, 2wd Hi, 4wd Hi, Neutral, and 4wd Lo.
NP205 cases had several different configurations with Ford and Dodge using both married and divorced models and GM using many different input spline types and 2 different bolt patterns.
The NP205 is identified by several features:
1: The transfer case is one piece of cast iron. There is a short bearing retainer/output housing at the tail of the case, and aluminum bearing retainers/seal retainers at the front and rear outputs but the working parts are all in a single iron housing.
2. There is a small idler shaft cover on the back of the 205 with 3 small bolts holding it on. This is somewhat unique among transfer cases.
3. The overall length of the NP205 (in fixed output yoke versions) is about 12-13" from the front of the case to the center of the output yoke.
4. The shifter is a very simple lever operating a crossbar between the two shift rails that plunge in and out of the front of the case.
5. The ID tag is found above the front driveshaft output, and will list model, manufacture date and gear ratio.
