Brake adjustment
For starters, which year car are we working on?? Your profile shows only a 1978.
Solid axle?? Early C2?? Assume you are talking about the primary car brakes and not emergency brake shoes on a 65-67 disc brake car.

Looking at the picture of the self adjuster you can see that the outside of the wheel will only rotate downward away from the lever. I assume you got the drum on and at least three lug nuts, on backwards, holding the drum to the hub.
Working through the slot, using a brake spoon, contact the star wheel and move the end on the spoon upward, which will turn the wheel downward.
I tighten the shoes until the drum does not spin and I hit the backing plate with a rubber or dead blow hammer to center the shoes. Then I readjust the star wheel, then I back off about 5-6 clicks untill there is light drag on the drum. Make sure you do this on both sides and back off the same amount of clicks.

Here is the star wheel and self adjuster lever:
Here is the special tool I use to grab the lever and pull it away from the star wheel to loosen the adjustment:
Here are my assortment of brake spoons:
Insert the "tool" in the slot, with hook up, and grab the lever and gently pull it back as you move the spoon down to loosen the adjustment:
