ccz is correct, however the newer panels can be used on the older door shells rather easily if using power windows or the newer regulators are installed (longer crank pin). You drill about 5 holes & use spacers on the bottom row of screws. The dashpad will not match the trim strip on the door panel unless you change the pad though.
Using the old panels on a newer door would take some work (closing up four or five 1" odd shaped holes) in plain sight & changing the regulators to the short ones... Not worth it unless you had a real good reason.
