any standard non vented 400 slip yoke will work. The out put you have is actually for a vented yoke, but your missing the retainer that seals the splines.
All you need to know is what u joint you have. Measure the cap dia and width, and note it its inside or outside retaining clips.

in english please? will it work if i just put a different yoke in it? or do I need another retainer? whats a vented yoke?
 
All yokes have a plug if you will at the end, so the oil does not leak out. Its similar to a frees plug. Some have a small hole drilled in the center, that would make it a "vented yoke" If you using a vented yoke, the output shaft must have a retainer with a o-ring on it to prevent fluid from leaking out the splines. Looking at your output shaft, you have a later model output that normally has the retainer installed. Yours is missing. Therefore, any standard turbo hydromatic slip yoke will work just fine, as long as its not vented.
I searched goggle and could not find a good pic...
