69 brake rotors?

Replacement rotors aren't sold with "hubs"
As airgrabber stated, people threw away the old rotors with the hub attached, and that's one of the reasons that hubs are pretty much, unobtanium, dinosaur eggs, and on the endangered species list, now-a-days.
Very hard to come across these days.
Lots of people are wanting them.
When i needed them in the past, for my brake rebuilding business, i found them extremely hard to find.
One of the reasons that i'm not selling complete disc brake set up's any longer.
