86 would be direct-fit because they are the same. For 87-89 front end conversion you need the front bumper, bumper cover, headlights and hood. Then you need to slightly modify the substructure to make it all fit right, just some light work with a sawzall and body hammer. Then cut and splice the headlight connectors and you're done. I did it all in an afternoon.
