It realy is easy.. Take the cap off the existing dist. turn engine over till rotor is pointing to fire wall...MARK the fire wall at point of rotor... Pull dist. out. Drop new dist. in and get rotor to line up with mark on fire wall by turning the dist. Drop it down making sure it (rotor) lines up where the old one was. You may have to turn the oil pump drive with a screw driver to make this happen. Change the primary wire
