Luke, I have some pictures. I'm not sure exactly where you are in your process,- if you're just changing your brake bands, or if you've taken off your drums yet or run into problems at that point.
Here's a pic of how I supported my final drive casting to extract it, using an engine hoist. The nice part is that you can raise or lower it incrementally to get it to exactly mate back up, and it's fairly well-balanced so that the differential shaft can go back in straight without any straining, or putting any sideways torque on the shaft.
My left brake band was saturated with oil- the right not so bad. But I thought that as long as I was this far, I might as well do all the seals at the same time. First step is removing the drum. It has a set-screw held tight by a jam-nut. Loosen the jam nut, then back out the set-screw.
The drum is not a press-fit, but it is keyed, and mine was on tight, and if memory serves me, I used a pry-bar in the lower right where it can be gotten behind the drum, and then gently pried, while spinning the drum to pry it 'all around', I was able to loosen it until it was able to be walked off the shaft.
Next was taking out the differential shaft. (I'm showing pics of the left side, didn't take pics of this process from the right, but it's the same). When you take off the cover (the only thing that holds the shaft in)...
the shaft and the bearing will come out when you *pop* the end of the shaft with a sufficiently heavy piece of wood. It is NOT a press-fit, but in a previous post, a guy's was 'stuck' somewhat.
This exposes the seal in the outer casting...
You can see mine was in backwards from a previous owner. The lip is supposed to face the oil within the casting where the bull gear is.
Here's the seal in the differential/tranny case.
I couldn't get it out without taking off the center differential housing..
which exposes the inner seal on the right...
But this takes special precautions, so if you're going this far, start another thread, (as this one is dropping) and we all can go from there.
I sent you my e-mail, so if you don't have dial-up, I can send pics that way.

Today's Featured Article - An Old-Time Tractor Demonstration - by Kim Pratt. Sam was born in rural Kansas in 1926. His dad was a hard-working farmer and the children worked hard everyday to help ends meet. In the rural area he grew up in, the highlight of the week was Saturday when many people took a break from their work to go to town. It was on one such Saturday in the early 1940's when Sam was 16 years old that he ended up in Dennison, Kansas to watch a demonstration of a new tractor being put on by a local dealer. It was an Allis-Chalmers tractor dealership,
