This topic has been discussed many times over on the old forum and you could do a search on 'disc' and find hundreds of posts. Many people advocate getting the spindles, calipers and rotors from a 70s-vintage Granada along with an early 80s (IIRC) Ford pickup master cylinder and doing home-grown conversions. However, with less effort and risk, you can spend $600-$700 and get a pre-engineered kit that will install and work perfectly and is absolutely safe. IMO, that is the way to go.
Just my $.02.
