Tourqing driveshaft center yoke

I have a problem right now, I don’t have a vice and or table to hold down the driveshaft to put the right tourqe spec on the center yoke nut. I’m thinking of maybe putting the front of the shaft into the transmission keeping the transmission in park that way the shaft won’t turn and try tourqing the nut to 130ft like that. Would that be to much stress on the parking gear and or is there a better idea?

 

I'd be leery of sticking it in the trans to torque.

How about a chain wrench around the shaft as a backup?

 

The parking pawl on the A750 Auto is beefy.
You ain't gonna break it at 130 ft/lbs.

What you don't want to do is take an impact to it.
That will beat the shit out of the pawl and possibly peen it. (doubtful).
Tighten it by hand the whole way.

And also the final torque is NOT 130 ft/lbs.
130 is just to seat the carrier.
