    <font color=blue>My front driveshaft is toast. I was thinking of installing one from a 73+ K5 since they're a little bigger and I dont quite have the $$$ for a High Angle shaft yet. At ride height the shaft I have in there now is 26" between the center of the caps. What trans/case combo from the 2nd generation K5s will fit? BTW I have a 465 trans and a 205 case</font color=blue>

    Probably one from a 2nd gen with the same tranny and transfer would be your best bet.

    <font color=blue>Thats what I'm thinking but I'm not sure if the front axles are in a 1st gen are the same distance from the case as they are in the 2nd gens, I just want to make sure. The main reason I stripped the splines at the slip yoke part (yes the shaft actually spins in itself [​IMG]) is because its too short and not as much of the splines are in contact with each other, so the load is not distributed throughout the whole slip part, just the part where the two sides are together. If someone with a stock height truck has a shaft just as long as mine, it may be long enough to go in my truck since the current one is too short.</font color=blue>

    I just put a shaft out of a 78 465/205 into my 80 TH350/205 which was 25 inches from the flang. The TH700R4/208 shaft version is 31 inches. I think the only thing that was different up till 80 was the tcase flang type, yoke or flat flang. I think trustyk5 has a yoke style for sale in good shape, send him a PM.

    <font color=blue>Mine is a yoke style. Anyone have one from a 73-80 TH350/NP203 lying around? I heard they're 27 1/2" in the middle of the slip.</font color=blue>
