1979 f600

Looking for a part number or name of the of those adjustment deals that insert into the front drum brake shoes ?
my front brakes are locked up I’ve replaced master cylinder
all wheel cylinders
hydro vac component
all vacuum lines
and the hydro check valve on the fire wall
bled brakes many times
I’m thinking since those things that go into the brake shed itself are gone that might be the issue ?

Before

Before

And getting closer

And getting closer

I think this illustration, labled page 21, shows your brakes. This is school bus site but the brakes are the same for the most part:

Here's a pic of a '79 dual cylinder front brake, looks like yours. You seem to have a lot of missing items related to self adjustment:

Brief explanation:

You need a shop manual or at least some clear illustrations if you are going to work on this truck, especially brakes:
