Disc Brake Conversion Kit (A-Body)

I really don't know much about these components. The guy I bought the car from planned to install them, but he rebuilt the stock brakes and the car is is really good condition, so I have them with no intention of installing them. Take a look at the link to the manufacturers description, and read the attached instructions. It looks to me like the rotors will need to be drilled to the 4" or 5" pattern, your choice.
