1971 k20 dana 60 parking brake levers help

[mattfrediani]

I have a 1971 chevy k20 and found the parking brake equipment gutted inside of my rear drums. I ran all new cables to the back but have nothing inside the drum to hook the cables. can anyone help me with the original GM part numbers for all the parking brake hardware inside the left and right drums from a dana 60?

I would be willing to buy the entire brake system or any parts needed.
I need these parts to finish a restoration and would be willing to pay top dollar or trade parts.

Thanks
Matt
