Re: Np203 ??
Copied this..
The easiest way to identify your transfer case, looking at the back of the case where the rear driveshaft yoke is located, focus your attention slightly to the right of that and if you see a 3-bolt cover about 2 inches in diameter it is a NP-205 (NP= New Process, as in the company that manufactured these transfer cases- New Process Gear.) If there is no 3-bolt cover it is the NP-203 full time. Np203
