Brake drum: access to starwheel?

[gman]

Trying to replace rear brakes but can't get the damn drum off. And the drum doesn't have the hole for backing off the little star wheel thing for the shoes. Its a stock K10. Where is the knockout for it? On the drum or the backing plate? Any suggestions on getting the drum off the rear end. I'm probably missing something here but I know someone will point it out. Thanks!
