I have a 71' f100 4x4 with an NP435 transmission. It has a married Dana 21 transfer case. I want to put an NP205 in the Dana 21's place . Can anyone tell me how many splines are on the output shaft of the NP435? I really do not want to separate the two to find out because it is still in truck and I use it daily. Any info. on this is greatly appreciated.
