I had extreme difficulty with the right back side on one of my '51 Frazer hardtops. I got the drum to break lose with the hub puller, but then could not pull it off due to the brake shoes being broken and binding it up. I then kept turning the puller to force the hub off and it worked; however somehow apparently I ruined the axle shaft threads and had to get another axle shaft and I got that from Rudy Phillps and he should be a source for drums if you cannot get in touch with Kaiser Bill.
