Tranny mount nut
 

Howdy!! This wasn't in the thread in the archive nor could I find anything by searching.
What is the size of the nut for the tranny mount? I'm talking about the big nut that goes on the bottom of the cross member that threads onto that big bolt that sticks out from under the tranny. I was transfering the mount assembly onto a new transmission and "misplaced" the freaking nut...so after about 20 minutes of swearing I came on here but couldn't find anything.

Oh btw, this is for an s4 manual tranny.

Thanks.
