I'm glad that you were able to remove your seal. I have a seal removing tool but I prefer the drum dropped on a piece of cardboard or carpet over concrete repeatedly until the bearing pushes the seal out.
I used the search option before I started the rear drum seal removal . there's a lot of different methods to remove the damaged seal . And if you are trying to save the seal slamming it on the concrete might work for you . It was one of the methods used to remove bearing and seal .
