A large pipe wrench works to hold the yoke.
that is what I use.
MoparX which third member are you workoing on?
If it is a "489" case then you need to know how much rotational torque is has both ways now before you loosen the nut up so you can tighten it back up enough to have 1 to 5 inch lbs. MORE rotational torque when your done
working on a 741 case that is still in the car Cab.
i'm not a fan of using a pipe wrench due to the possibility of the teeth marking up the yoke.
i had thought about making a tool like the several that have been shown. i'll probably do just that, although as i get older, i find there is no such thing as a 5 minute [or 5 hour for that matter] job.
