So let me get this straight. For the 6th Gen.

1998, 1999, 2000 Coupe: Bumper has no fog light slots
1998, 1999, 2000 Sedan: Bumper has no fog light slots
2001, 2002 Coupe: Bumper has the fog light slots
2001, 2002 Sedan: Bumper has no fog light slots

The sedan bumpers for all 5 years can be interchanged. But if I wanted to put a coupe bumper on a sedan then I have to replace the hood also.

In my case, since my car is a 1999 sedan, my only option to get the bumper with the foglight slots would be to get the 01 or 02 coupe bumper and also replace my hood to avoid any gaps.

Correct me if I am wrong
