66 Fury III spindle replacement

So I am learning as I go with this car I purchased. I luckily have a neighbor who has been around the block and is giving me some guidance. He was telling me that if I wish to upgrade to disc brakes, I will need to get different spindles for the front end. I know there is a conversion plate from scarebird, but what spindles on existing cars that I might find at a salvage yard would fit the 66 Fury? He mentioned I could save a lot of money taking them off the front end of a junked car.
