Demon brakes

[Toms70Duster]

I'm working on a '72 Demon that has 9" drums on the front. I want to change to big bolt pattern disks. I'm looking for a donar car so when I find one, what do I need? Can I use any of the parts that are currently on the car?
Thanks,
Tom

If you go with discs on a '72 or earlier car, you will need everything from ball joint to ball joint and the master cylinder, but can keep both control arms. The '73 and later option requires '73-'76 upper control arms (not necessarily from a disc brake equipped car) as well, and has a large bolt pattern.
