Okie here is the situation.

I pulled a diff (housing also) out of a S5 Turbo. I had an FD torsen's guts transplanted into the S5 housing. At this moment, the S5 output shafts aren't seating in the diff now. If I push them in any further, the stub will grind against the housing. Which stubs are supposed to be compatible in this situation?

 

come on... nobody knows this?

What about all the people that say "ooh... it's a direct swap." I'm finding that statement to be total bull at this point.
