It's been a long time since I did brakes like this, but I think Hector is telling you the studs don't go under the drum they stay on the back side.
Hook up the anchor plate and you will see this.

There is a copy of the D7 17A service manual in the ACMOC library. You have to be a paying member not just a freebie user to access it.
Here are the pages for the brakes:
