The Kelsey-Hayes Disk Brake Swap Thread

Hey guys,
So, if I have the 10 inch front drum setup on my 67 cuda, then I would need different spindles to go with the Kelsey hayes setup, right?
I have:
Both calipers
Both rotors with hubs attached
Both backing plates
Mater cylinder and power booster
Proportioning valve
Bearings and caps.

Are the spindles available?

Do I need anything else?
Thx!
