3speed manual to C4 help and parts

[SuperSession74]

Hey all just purchased a C4 out of a 73 and plan on doing the swap into my 74. The C4 has the stock adapter to the Dana 20 but the seller did not give me the output shaft/coupler to mate with the c4. Thought that he was including all parts and or TC . Would have purchased from him but apparently the TC was sold to someone else and probably wont be using the parts that i needed anyways lol.I have read that I can use my manual one but will need to be cut down. Is that correct and approximately how much would need to be cut. Also is this done with say an angle grinder and would the shaft need to be pulled out to do this or can it be left in place. Also is there anything else I need for mating the two say bearing, retainer,seals ? And anything I should do as far as replacing seals,bearings etc. While apart. Also if anyone has what i need Auto style output shaft etc. Much appreciated. Tony

You have to take the shaft out because you shorten it from the adapter side - you're cutting off part of the female splined end.

Most of the vendors sell the correct auto spud shaft.

Cool so I can shorten mine or purchase an Auto one everything else is ok to use then ?

I'm in the middle of the same project. This site will help in identifying the the big items needed. So far with the help of this site I have had everything needed except for a few small surprises. I was disappointed last night when I didn't have the nuts needed to mount the torque converter. And I also need the bolts to mount the neutral safety switch. Hoping to attach the tranny and t/c in the next few days.

Now do also need the Auto bearing retainer aswell or just shortening the spud shaft is all that's needed ? Thanks

Bearing and retainer should be the same.

Thanks !

Anyone know the actual difference in length? I have access to a machine shop so I'd rather shorten than buy. Also I have a spare spud shaft that I can't remember where it came from so it could be a C4 version.

Thanks

Searched some old threads and found the answer:

C4 spud is exactly 7 3/8" long. Manual spuds are about 1/2" longer.
