Can someone tell me how to identify my transfer case?

203, 205, 208... I know the differences between them but how can you tell them apart visually?

The cases should have a tag on them. The 203 and 205 have a cast iron case and the 208 is aluminum.

88 208

The easiest way (to me) is the shift pattern, and case construction. Your truck most likely would have a 208 case. The shift pattern from top is 2hi, 4hi, N, 4 low. The shifter is mounted to the cab floor, instead of to the case itself.

Np 205 is that the one with the chain but more importantly where can I find a how to manual to dropping the tranny and transfer case down safety

np205 = part time gear to gear

np203 = full time gear to gear range box and chain for the front output .
