they stick out more (wider plastic outside) but are also more narrow at the bottom (97+ have a nicer shape imo). Also u cannot swap the 97+ style into a car with the earlier style grilles without changing the entire nose panel, since the shape is different. However if you just want the wide plastic look you can order something like that on ebay to fit the 1992-1996, they just won't have the nice narrower look at the bottom. Basically the older grilles are more square shaped and have a much thinner chrome around than the newer ones.
I'll find pics.
Heres a pic of the 97+ style (sorry for using this pic I don't know who this car belongs to, I think I saved this one from bf.c but I guess the car could belong to a max member)
Heres a pic of my car rockin the 92-96 style kidneys
