Looking for front disc brake set up

I'm about to replace the front disc setup and spindles on my '69 dart with a Wilwood setup and drop spindles. I don't know if they will work on a '64. But if they do, I've got 2 sets of spindles, lower ball joints, rotors, brackets and calipers. I thought they were Kelsey Hayes but they are BB pattern I believe. I was told they were original to the car when I bought it. I'll be getting into it this weekend. I'm in San Diego.
Let me know if these might work or exactly what you are looking for.
