As you said, the first one you listed was the OEM "Chin spoiler" (I have a painted one on my car) and the second one is the OEM "Front Under Spoiler". You can still get the chin spoiler, but the OEM Front Under Spoiler (and the rest of the body kit for that matter) for '96-'98s have been discontinued for about 3 years at this point. I got my OEM rear lip in May of '02, and it was one of the last ones available anywhere. Your best bet is to just get a CTR replica lip from a reputable place. If you find a decent one, it will be near OEM quality, and will look the same.
