On the 59 Chevy 10400 that I had, I had to do the same thing on both rear drums. Jacked it up, pulled the wheels, removed the axles and outer bearings. Then, I took some 1/2" socket extensions and worked them into the opposite axle. Once seated against the axle, I had a crowsfoot puller (the kind you use to pull a harmonic balancer) that just fit into the bolt pattern of the drum and cranked it up hard, used a big hammer and after a bit, they finally walked off. Fun job.
