Question 1987 Mustang Harmonic Balancer Question

I'm changing the Harmonic Balancer on my 87 Mustang.
It's an AOD Transmission car.
How do I keep the crank from turning when uninstalling and installing the the balancer nut?
Also, how do I change the front seal?
Thanks for the help!

I just used an impact gun and it turned the nut right off, I had the belt still on.

The front seal.... hum I do that when the motor is out, because if I remember the front water pump cover is in the way...

How about reinstalling it?
I don't think I can have the belt on when doing that.
The seal behind the balancer is what I was referring to. I was probably wrong in describing it.
Thanks for the help!

I don't have an air gun. I'm using my torque wrench.
So , how do I keep the crank from turning when I'm tightening the balancer bolt?
Do I have to get a flywheel wrench?
What's the best way to put in a new crank seal? Part number on the seal would be great also.
Thanks for the help!

I have an old belt that I cut so it's a single length, wrap it around the crank pulley and then wrap the other end around something secure, if necessary just make a noose with vice grips and hook it around something secure (like another pulley).
