Parking brake components

[Kenfuzed]

I recently bought a 66 C10 SWB that I'm in the process of putting back together. The PO appears to have remove almost all of the parking brake parts. All that remains is the 2 rear cables hanging out of the drums (zip-tied to the frame) and the lever under the dash. I don't see any remaining brackets or hardware so I'm starting from scratch.

Does anyone have a list of all the parts I need and if any vendor sells all of them still? A parts manual is next on my list but I was hoping to get an accurate list so I can just buy everything I need all at once.

Current truck specs: 1966 C10 fleetside shortbed, th350 auto, 6 lug rear drums. Unknown what is original and what is borrowed since the front clip suspected to be from a mid-70's truck (5-lug disc) and the trans cross member looks to be changed (different shade of dirt).
