I can find plenty of kits. I specified I wanted to source these from a donor or two.

This isn't a kit.
It's spindles and rotors.
They rest can be sourced locally at your parts store.

IF you want to use a donor.
Use 71-72 truck parts or 73-87 truck parts.
Swap the entire crossmember assembly and then add these rotors.

MY OPINION,... all donor parts are wore out junk.
All tie rods, ball joints and bearings need to be replaced.

I was trying to help you by NOT mixing and matching parts.
Conversion spindles are the best answer for 60-70 drum brake truck owners wanting disc brakes.
No ball joints to change.
No tie rods to change.

Sorry I wasn't helpful enough.
Can someone else help?
