65 Commando stock brake set up

As some know I picked up a 65 Commando about a month ago that has set for 30 plus years. Drums are stuck on, but managed to get the back two off finally. Finding nine inch drums on the car, and I don't think that is correct. I might add that the secondary braking material came off with the drum on both sides.

Thinking maybe since I had power brakes the drums were correct I bought 9 inch drums and 9x2 brakes. First thing I noticed was the shoes coming off the car had more braking material than the new ones. Same 2 inch width, but more braking surface length on the old shoes. Other things I noticed missing according the 65 service manual:

No push rods on cylinder
No parking brake cable and guide
No star wheel lever. (nothing to auto adjust the star wheel unless you crawled under the car and did it yourself)

I've bought these parts to try to put the brakes back together as the service manual shows, but now I'm second guessing rather I have the right drums and brakes, and rather the original brakes had these missing parts.

Can anyone comfirm that all V8 cars should have 10 inch drums? I'm measuring internal diameter and the ones that came off are only 9 inch. Is there a way to tell what should be on the car by measuring the backing plate? I'm starting to wonder if I had 10 inch brakes inside 9 inch drums. Also can anyone confirm stock set up on the push rods, parking brake cable, and star wheel lever?

Thanks!
