Converting to a C4
So if I were to convert my 69 from the Manuel 3 Speed to an automatic, would it be wise to buy a stock C4 out of a Early Bronco or some other model of automatic?
I may have found a stock unit in a wrecking yard, at this point the price is unknown, I should here from them next week.
If I buy the C4 what other parts do I need to install it?

The Early Bronco one would make it easier and it's better than a car C4. Get the adapter to the tranfercase if at all possible. It covers the c4 tailshaft and connects to the transfercase. You will also need a torque converter, flexplate,and some kind of shifter (floor or stock column).Not everyone puts them on but a kickdown rod is good to have on.

The guy at the wrecking yard is going to check on the adapter on Monday. What about transfer case input shaft are they the same?

The factory automatic stub shaft is different from the 3 speed. If you use the Advance Adapters kit, you shorten the 3 speed stub shaft. I'm not sure how much you remove or if you could shorten it to work with the factory setup.
It is also a minor point, but be sure to get the flexplate attaching bolts for the automatic. The manuals are longer and will bottom out before tightening the flexplate.

This is the part that has female splines that slide over the transmission output shaft and male coarse splines that slide into the transfer case input gear. It is essentially the transfer case input shaft.

OK Thanks guys, So the way I see it, is that the spud shaft is part of the transfer case and the transmission has the female spline in it. Not that it matters as if I buy the transmission I need the shaft. I have not herd back from the wrecking yard yet on the price, I meant to call them today but got busy at work and forgot.

The "spud" shaft is in the intermediate housing connecting the transmission to the transfer case.
There are different lengths too.
The six cyl 3 spd has a shorter intermediate housing than the V-8 3 spd.
I would *assume* that the "spud" shaft may differ between the two also as well as the auto tranny version.
The transmission output shaft goes to the female on "spud" shaft, then straight through to the output shaft & rear driveshaft flange at transfer case.
Regards
Ken

The C-4 spud shaft for the Bronco is specific to this trans. It is part of the trans. The unfortunate thing is it is the first thing that goes in and the last to come out. In other words you MUST completely disassemble the tranny you get from the junkyard. Also the spline count on the input shaft Must be counted before you get a torque converter. I have done several swaps. Try Tom's bronco PArts...He has them complete. Also Broncitus has them...
