Please post a picture of what you refer to as a "plate garnish" being that these Civic dont have one it must have a different name.
I assume you're asking for info. on where to find one since this isnt the sale section and you dont meet the requirements to post a "WTB" request.
By the way, I tweaked your title because "Looking for 96-00 Plate Garnish??? Help?" is the equivalent of "Are you looking for a 96-00 plate garnish?" and you're clearly asking for a part and not offering others where to find one.
