Hy txpete, brake drum removal can be a patience tester. If you have to resort to a puller, something will probably end up being damaged if not totally destroyed. If you remove the outer rear wheel bearing you can pull the hub with the drum on it. If you find a thick piece of steel that will span the opening of the axle tube but allow the inner rear wheel bearing to pass over it you can use that to press against, you can use the axle studs to attach the puller, you may have to remove the original studs and install some longer ones, hope that helps.
