Front end swap

Just double checking something. A front end, headlight area and the like, from an 83-87 Camino will bolt right on to an 80 correct? has anyone done this themselves and if so, what problems did you encounter?

1978-1983 Malibu and 1978-1987 El Camino, will interchange. This is for entire front clips. Keep in mind that through 1981, these cars had single headlights on each side, two in total, while 1982-up had dual headlights (4 in total).

Yes, they did have four headlights. Is this a major electrical problem or something fixed with a simple splice?
