1966 Mustang Disk Brake Conversion

The fastback came with four-wheel non-assisted drums. The stopping power was... unimpressive. Fitting the spindles and rotors from a 1979 Mercury Monarch was straightforward, with the following exceptions:

• hub diameter on the rotors much larger than the drums - needed newer wheels
• outer tie rods from the Monarch had a greater overall length, prevented setting toe-in - had to trim them, and their adjusting sleeves
• bending brake lines for the new master cylinder
