You need the distributor, cap adaptor, rotor, cap, leads, module. Most will be supplied with the wrong advance curve. :roll: That means it's advisable to buy a re-curve kit.
Some people use the GM ignition module instead of the Duraspark box. They also choose a hotter Ford coil - the "TFI coil". One website that details this alternative implementation is gofastforless.com.
