Custom aftermarket grille?

The following website has 2 replacment grilles for the 91-92 models: http://replacement.autopartswarehouse.com/parts/autopartswarehouse/wizard.jsp?year=1992&make=BU&model=PARK--001&category=All&part=Grille%20Assembly&dp=true
I don't see how that one pictured underneath the factory style grille (#BODB051C) will fit? It looks totally different, flat and curved and obviously has different mounting areas for the bolts...am I wrong? Has anyone ever seen a grille like this?

Looks like the lower one is for the 88-90 PA. Why would you get the regular replacement grille? go on ebay and look for the ultra grille, it looks alot better.

Hey tman thats actually what I had planned, I really like the Ultra style better myself. My wife drove into a big shrub when parking (she's used to parking her Saturn and I guess she misjudged the distance in my Buick) and cracked the high-quality plastic grille! I am browsing through every site I can but they are all showing the exact same grille# for base and Ultra models. I'll try Ebay but I tend not to have much luck with that site.
