I got a sedan grill that I just happen to come upon on ebay a couple years ago, it is similar to the coupe one but the opening for both is different, also with your grill it may be a bit hard to do since it sits flush, on the 01 and 02 bumpers the grill is set back. If you could find a sedan grill you could probably do it but trying to find one could be really hard. BadderType did it with your same type of bumper, you could try and see what did. Let me know if I can give you anymore help.
