I would like to replace the front drum brakes on my 1970 Roadrunner with disk brakes what do I need for this? Also who knows about Power Stop brakes?

I used a kit like this to swap over a 67 Barracuda. Everything was included. The only issue was having to elongate a hole in the backing plate. Looks like all factory style parts. fit well.

As stated keep it factory, you wouldn't believe the headaches you will save your self.

DR DIFF.. Very nice set up,,

Went with spindles from F,M,J . . . used ones with calipers on rear side . . . made sure to get correct calipers with bleeder on TOP . . . and used aluminum master cylinder with adapter from Dr. Diff . . . manual drum brakes to manual disc/drum . . . works great actually, no issues at all . . . oh, also got the braided brake lines from Dr. Diff also . . . over 10k miles on car now, no wear issues on tires, brakes work great.

Thank You I am looking at this now

our good Doctor is great to deal with !

All the factory disc brake master cylinder do NOT have a residual valve in the master cylinders to keep residual pressure on the disc brakes, make sure yours doesn't have it when your ready to drive it. It is a little rubber flapper valve with a tiny spring in it that sits behind the brass insert for the steel brake line to seal against, I use a #8 sheet metal self tapping screw in it, 2 to 3 full turns, and a claw hammer to pull the screw out with the seat on it
Make sure and tighten the seat back into the master cylinder and use a lot of pressure to reseal the seat up again
