I thought that lip was made for the 99-00??? If not, Im pretty sure you can get it "molded" to fit on the bumper. I know Drackkon had a lip spoiler, made for a Honda nonetheless, custom fitted to his bumper. Looks really good. Im sure you can him about this and he could answer your question.
That lip is for the 01+ which every ******* part is made for. Im going to get it and customly put it on, its just a matter of where i can get it for cheap/.
Depending on what you consider "cheap", Im sure one of those sites have it/can get it for you. JONBOY688 works at a Mazda dealership and seems to get a good discount on Mazda Parts. Maybe he can save you a little money.....? Let us know whatcha do.
*Edit*
You also may want to look at the new sedan lip that desy and his people finshed up making. Looks pretty good in my opinion. Its like an AutoExe replica, but a little bit different. Check it out!!
