Since I broke my 9/16" socket I purchased a set of 12 point impact sockets. A cheater on the end of the breaker bar did the trick and the bolts broke loose. After quite a bit of scraping and wire wheeling the hubs cleaned up nicely, I also cut off the "nub" protruding at the mounting surface of the hubs. After the hubs were thoroughly scrubbed with lacquer thinner they revived a coat of self etching primer followed by a couple coats of engine enamel.
