To anyone interested, I just received a yoke (from a C6) for my T85 (passenger car) and it fits perfect.

ebay item #190296112754

Here are the numbers...

These are new slip yokes for Ford C-6 transmissions,

they have been sandblasted and sprayed with a rust preventive coating.

2-3-3131X

1310 Series u-joint

1.390" 30 based on 31 spline

1.685" ground hub diameter

1.150" counterbore

6 9/16" U-joint center to end

After a gift certificate from paypal, I paid a little less than $10 altogether. This is a nice piece.

In fact I'd trade them for a good T-86 that would bolt right in ..

Thank you very much...Mark

Just the fact that the R11-1 E and also the R11-1 H were 1956 installs only for both the Merc and T Bird according to my documentation.

Thanks Oldmics.

I was going to install it in my '55 Sunliner but I've desided to use it in my '29 Model A Roadster behind a Y-Block.

What numbers indicate 1956?

I have 2 T-89's the truck version of the T-85. One has a spicer yolk and the other one has a slip yolk. Mine is broke but it's a 31 spline. It's good to know a C-6 will work. My main problem is I need a 6" input shaft as mine's 6 1/2. I think T-10 stuff may work too. I'd trade my 2 T-89's for one good T-85. One of mine is a short tail shaft and the other one is a long tail shaft. One is basically a parts tranny and the sun gears are shot ..

I should have also asked what sort of machine that this tranny is being installed into?

What we have here

is a 1956 O.D. slated for installation into a T Bird and some Mercurys.

The T Bird tranny was adapted from the Mercury.

The Ford part # for the yoke you need is

B6S4841-A

Hope this helps

Here are all of the numbers on the transmission.

Trans case    T85C-1A     6-14 on a small plate riveted to side of case.

Tailhousing      R11-IE        7-12 on riveted plate

input collar    T-85C-6

Spacer between trans case and tailshaft   R11-8

Solenoid  1119779

Input shaft   1" diameter    6" long    10 spline  

Output shaft  1.37" diameter   16 spline

Length of trans case, spacer and tailhousing  30 3/4"

H1952 stamped next to side cover on the machined surface.

The T 85 is the transmission designation.

You then have to add in the tailshaft consideration-in the case of the O.D. unit its an R11.

Your concern is to get a driveshaft yoke for a T 85 O.D. transmission with an R11 tailshaft.

The T85 transmission with the O.D. and the R11 tailshaft came in both spline counts of 31 and 16 depending on what year it was built, application and as to what it was installed into.

Best to measure the outer size of the tailshaft spline and start from there.

If you give me the outer size I can give you the Ford part number (its in the book) but then you will still have to find the actual part.

I just got one from eBay for $30.00 but it was a crap shoot for me since I did not know weather it was going to fit since the measurements were not listed in the add.

I will have to look regarding the fit to the T86 trans and report back.

Also can you post the rest of the information (numbers) on the tailshaft.It decrees length of the tailshaft and I want to compleatly understand what you have.

So the T-85 and T-86, with or without overdrive used a 16 spline yoke?
