That rear end is probably from a Lincoln, or maybe a big Mercury. It has a flange instead of a yoke. This is only half of it. The other half is still on the drive shaft that went with it.

You can use a yoke from any Ford car or truck. The car yokes are longer than the truck yokes, and they are made for 1310, 1330 and 1350 series u joints. Your TH400 yoke may be for a 1310, 1330 or a 3R u joint. I recommend finding out which joint your transmission yoke uses and get a yoke for the rear end to match it. You are having a new drive shaft made so it doesn't matter if you use a car or truck yoke. The truck yokes are easier to find, and if you get an after market yoke it will be the shorter truck yoke.

I would look in the pick-a-part for a driveshaft with the flange that fits what you have. then have the driveshaft guy fix your shaft with the proper ends..Mine for example has the ford rear yoke to fit my 9 inch and a gm yoke on the front end to fit my t-400 trans..works fine..Hope you understand what I am saying..Most likely your driveline guy will know how to do this..

Depending on what series the rear of you driveshaft is.. You could get a flange yoke similar to Spicer 2-2-1379. I would need the bolt circle off your pinion yoke to give you the exact part number of what you need.

A flange yoke is usually cheaper than a pinion yoke so it may save you a little.

Your driveline builder/supplier will usually have those flanges in stock, and cheaper than getting a complete driveline from a wrecking yard. I found out the hard way, as I got a driveline for mine with that same flange for $40, and then had my driveline assembled and was told they had new ones for $35.
I'd measure the bolt pattern to ensure you get the correct pattern. (I think there's only two patterns) Then call whoever will do your driveline work, and get the flange first. Then with the flange and yoke in place you can measure center to center on U joints to get the length. After that your driveline shop can make it up with the proper joints.
On my Falcon's driveline I had a Super T10 four speed, so had a TH400 style spline up front, and a Explorer flange at the rear. Once I got both in place I found the length was the same as a 1st Gen Camaro/Firebird, so I bought that driveline for my car. Took the yoke, driveline, and flange to my driveline shop, and they charged me $43 to install two adapter joints to make it work.
