Hello, Elko. How are things at the Star? I liked the basque dinners there many years ago.
One thing to consider regarding getting the back drums off the big iron... My left rear was locked up and I couldn't get the drum off after removing the nuts and all. It turned out the emergency brake mechanism was corroded and locked in the "on" condition even when the cable was slack. I soaked it and tapped it with a hammer to work it loose. That released the shoes and the drum came right off with a bit of tapping over the shoes. It's worth a try if the drums refuse to come off.
