    I need specs on the output shaft from a th350 that makes it combatible with a np208. splines, length, etc... The 208 is in an 84 k5. I'm modifying a turbo 350 to match up with the 208 and am having trouble finding the correct output shaft. I think the shaft that's in it is for a np205

    OK I found the spline count I need. (27) Just looking for the length the shaft should extend out the back of the 350 to make it fit the np208.

    Yeah, that's what I plan on doing. Just trying to figure out what to look for. The th350 I have is from a 4x4, but I think the shaft that matched it to the np205 is going to be too short. Haven't found one matched to a np208 to get a shaft from.

    the 203 and 205 versions are very short and the 208 versions are very long. i can't rememeger exactly but my adaptor measures 5". best to get one specifically for a 208. i don't think anything else exchanges.

    Yeah, The person I'm getting the adapter from gave me the same measurement, so now I've just got to find the right output shaft.
