I've used the 3-spoke drum puller, if you don't have one you might get on from O'Rielly's, Carquest or even Auto Zone, several times over the past 24 years while owning Kaiser cars. Works good. Here's how I do it. Remove the effected wheel, remove the retaining nut and flat washer, turn the nut over and install it backward on the end of the a xleshaft until it's flush with the end of the axle but not against the drum. This will prevent the end of the axle from swelling/damage. Then install the puller using the original wheel attachment bolts. Now tighten the large bolt using an air driven impact wrench if you have one. If not then stick a crow bar or some such tool thru the spokes of the puller. Now tighten the center bolt as tight as you can, don't use a torque wrench, and then with the opposite wheel off the ground, hit the end of the center bolt with a large hammer, and I mean large. Several hit's may be required while retightening the center bolt between each hit with the hammer. The drum should pop off at some point with out having to heat the hub. Then you can remove the puller, the drum retaining nut and and then the drum. If the drum won't come off then you will need to back off the brake shoes a little.
Note: I've been using one of these since I was about 12 years old in my dad's garage. Hope this will be of some help.
