    I have an '81 K5 with a TH350/NP208 combo. My T-case blew up on me and I need to replace it. My question is, is a NP208 off a 700R4 the same as the one off a TH350? In other words, is it a direct bolt on or would I have to modify one off a 700R4 to work on my TH350?
    Thanks in advance
    Jeff

    i believe the only difference might be the output shaft, I don't have a 208 so not sure, but i think that is what i hear floating around here.

    The output on a 700r is longer then the th350 so look in to that

    if the shaft is the same , just keep the adapter that is on there and stick a new case on . cuz i know the adapters are different lengths , hence output shaft differences.

    Right, the output shafts and adapters are different lengths, but the transfer cases are the same.
