1970 Drum brake question

[gsxrdoug]

Ok I feel like a tool asking this and I looked on the inter web and on here. I can't seem to get my rear drum brake covers off.

I read the manual and it says it should just pull off once the wheel is off. No such luck.

I read also it said I may have to back the shoes off but not sure how that is done.

I've done many VW Bus brake jobs and there was a little wheel you spin inside the hub but nothing like that on these it seems.

Any help would be appreciated.

1970 C10 regular L6 drum all around.

Thanks all.
Doug
