Re: 3 speed to auto driveshaft ?

Does it have the three spd saginaw transmission??And your swapping in which automatic? If 3spd to a th350 If so, you should be able to just pull your manual trans, and swap the autoin it's place. The driveshaft should be the same. you'll need an automatic crossmember for trans.

Re: 3 speed to auto driveshaft ?

There are three different lengths of TH350 trans too, so you can't just generalize what will fit. You need to measure your current trans versus the new TH350.
