If you want to stick your head under neath your truck, and look at the transfer case to see if it is an NP208 or an NP241, and you don't want to actually crawl under there and wipe the grease of the round tag that tells you exactly what it is, just look at the out put of the transfer case. An NP208 has a large one piece output housing. An NP241 has a 2 piece output housing. There is a small extension, that bolts on with 4 bolts.
