I know right!  I was dumfounded after checking my wrenches multiple times.  I may check an adjustable wrench, not sure it will fit though...we'll see.

In the past I’ve gotten a wrench on, then shoved a screw driver between the flange that the ujoint connects to in order to apply torque to remove the nut. Might help you out. 

I have seen rare cases on other vehicles where they are a ?/32nd size. I think it was done to make them smaller for the desired location. I have enough SAE wrenches to come up with something that fits

Original fasteners are definitely M8 with a 12mm hex size. To get a 12mm wrench on, I had too do quite a bit of cleaning first, but it did go on. A 15/32" wrench would not work, as it is slightly under 12mm, 15/32 = 11.9mm. If I remember correctly, I also had to use a wrench with a thin cross to get in there on the diff side.

Late to the party but get one of these for the transmission side. Keeps all that stinky fluid from spilling out.

Great idea!  I've had all the fluids drained from the entire car so not necessary for me this go-round.
