    There isn't neccessarily years that had it and years that didn't, because they made both at the same time. You just have to figure out if the individual trucks you look at have it. Be aware that a part time truck may have started out full-time, and have a converted NP203. You'd probably be better off with a NP-205, it seems to be the general concensus.

    easy enough 69-72 only came w/ an NP205, unless you are unfortunate to find a K5 w/ I6 and a dana20.I believe the NP203 was offered 73-78 timeframe, maybe 79 also.

    I can confirm 79 K5 came with a 203, I have one. I picked up a3/4 ton drivetrain to swap in. Generally pre 1980 if it doesn't have selectable locking hubs it's probably a 203.

    I also love the body style of the first gens. They're out there, good luck on your search.

    Full time trucks were offered from 73-79 but, as stated, it was an option so not all trucks in the period were full time - yu're going to have to look at the t-case.


    If you want no chance of a 203 in the 73+ body style look for an '80 (GM only used the 205 this year).

    most any 1/2 and 3/4 ton 73-79 is 203 equipped, a few 1 tons 77-79 and a select few 80 ones

    oh and gm called the straight six engines L-6 back then, not I-6

    and the dana 20 was a extremely limited case, ive looked in all the 6 years of gm ordering specifications sheets books i have and they all show only the 205 available cept for 69, im trying to find the 69 one, i believe its the only year that the 20 case was available in gm, otherwis everything was 205 equipped, no matter the engine or tranny ordered

    good luck

    make sure you crawl under there and check out the tags....I have no clue what the fulltime setups were like but i know if its a transfer case it has a tag.

    The only case GM used in '80 was a 205 (regardless of options/vehicle type), they stopped using the 203 in 79.

    The vast majority of '73-'79 trucks with an auto trans were full-time 4wd with the 203 t-case, and the vast majority of manual trans trucks were part-time with the 205 t-case.......though there are exceptions. Another thing to keep in mind is that these trucks are around 30 years old and may have been through several owners, so it's really hard to tell what parts have been swapped in and out.
