That's how I installed it.rotated the front two and connected the rear band.vut the rear band studs will not pass under the drum.

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:

It won't rotate far enough to install the anchor pin.the studs on the band need to go under the drum.manual shows the studs on the rear band in front of the drum.i reinstalled the old band to see and they are definitely at the front side of the drum.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
