As for the tailights without the orange turn signal(what you call the "grey taillights"), those are also from the SE-L, and maybe on the '99 SE too.

The SE-L is a 99 SE, that is the only model year sentra that is reffered to as a SE-L. The 98's are only SE's. That is why the 99's have the SE-L badging and the 98's dont.
