I need to know the correct yoke length for a Super T-10 transmission. I sent my Son's T-10 off to get rebuilt awhile back and think I got someone else's yoke back by mistake. From what I remember the yoke I had originally was quite a bit longer than the one I have now and I'm a little worried if I run the short one I might have some bushing problems if it isn't right. I've been browsing the internet trying to figure out what yoke this trans calls for but can't seem to find any info. Ebay is offering numerous yokes that say they fit the TH400, Muncie and T-10 but I really think there is a length difference. Does anyone here know for sure if the T-10 takes a specific length yoke? Are there length differences? Thanks in advance for any info, or links, Bob

It seems there are 3 lengths from center of cup to end: 5.5", 6.75" and 8". I guess you could use any as long as your driveshaft is the correct length and the right size u-joint.

I currently have the short 5.5" one in my Super T-10 and it is fine. The yoke is the same length as the 27 spline one it replaced when I swapped out my Muncie for the ST-10.

The bushing in the trans is about 1"-1.25" wide and it sits about 1.25" deep in the tailhousing. So anything over 2.5" in the tailhousing is beyond the bushing. I have one of the 6.75" yokes I got by mistake and it will go into the trans all the way without hitting anything inside.

Yep, matters not. So long as it's a th400 yoke you're good to go.

Excellent, this is exactly the info I was looking for. The way the car (70 Nova) sits right now the yoke is sticking out 1.125" from the housing but the car isn't completely assembled and the leaf springs are new (expect them to settle some) so I think all will be OK? I definately had the longer yoke when I sent this trans out years ago and it raised some question if the shorter yoke will work-Thanks for clearing this up.

Hmmm, there are some of those yokes for trucks that are very odd and bolt to the output shaft, that might be a little different. The splined portion of the output shaft is fairly long and it is better to have more engagement of the yoke than less so I say it does make a difference.

The face of the yoke should have at least 3/4 inch spacing at ride height, not rear hanging while car is on jack stands height. The spacing should maintain through the complete travel of the rear, changing a slight amount as the rear travels through it normal arc.

Do not put the yoke tight to the back of the trans, it will fail and break the extension housing.

Specifics Wally. jeez. Yes as Wally said don't get a th400 yoke with a hole in it.:thumbsup:
