Proper 8 1/4" Rear Brake Drum Adjustment Tool?

It doesn't wiggle. I'm going in for a leaking axle seal anyway. Looks like I'll pull the axle with the drum, and separate them off the car.
If you can't get the drum off because of the brake shoes pulling the axle won't help. You will need to take the backing plate off as well. And then you still have the same issue of not being able to get the drum off but now instead of being attached to the rear end it is now laying on the garage floor.
