CMP chev parking brake hardware

[patallen]

Hi, i am fixing the rear brakes on our missmatched CMP and apparently there is some missing parts in there to re enable the parking brake function.
Tehre must be a lever that attach to the shoe somewhere and other misc hardware.
I would like to get pictures if possible to see whats missing in there and potential sources for theses elusives parts, including the cables as well.

I have rebuilded cylinders on the way and relined shoes soon.

Bob..?
