[Low & Slow]

So fixing up the c10 I recently acquired and while inspection the rear which the previous owner swapped in I noticed that there were no rear parking brake cables going into the assemblies. Nor is the adjustment bracket under the bed.

I can find the cables online but I need the whole assembly. From mid cab back to the adjuster, all the way to each hub.

Any ideas guys? Can other year Chevy parking brake components be used? Are the adjusters basically the same assembly? Any problems buying these parts used?

Thanks!
