Rear disc brakes?

[Slofarmtruck]

I tried the search function already before I get yelled at. Perhaps my key words were incorrect. Regardless, for my 86 C10 I would like to install rear disc brakes. Is there a budget option for this swap, or do I need to purchase a kit from a vendor? I am just wondering if say rear disc brakes from any other GM vehicle will swap onto my rear end? Any and all info with and without pics is greatly appreciated. I don't have my truck out form storage yet, but I know it needs brake work so I figured why not upgrade while I am repairing. Thanks in advance.
