If your rear springs are like mine and most other 65/66 Mustangs, they already sag more than inch anyway! I put coil helper springs on mine to restore it to original height, but since my car is not drivable yet I can't say whether these affect the ride or not.
As for the brakes, I don't know if the 67 & up master cylinder will bolt right up, maybe Twister or someone else knows. I would like to know the answer to that question, too. I just bought a used vacuum power booster so I can add power brakes to mine, but it is the vacuum power so it is made to use a single master cylinder too, so if someone out there knows a good upgrade for you, maybe it will work for me too.
