I know they are not a direct swap, but many of the attachment points (especially at the top of the grille) are the same.
The '92 and up grilles have their lower attachment points on the face where the '85-'91 grilles have them on the lower corners.
That's probably not a big deal to get around.
I don't know the details on the headlight trim.
I know that both styles mount with four screws each, but I don't know if the holes are in exactly the same place.
