What is the difference between the black lower inlet and the white lower inlet? The pic of the black inlet is my SC, but I like the way the white looks a lot better. Is it something like a grill insert that I can buy and put in or what?

 

First SC is 92-94, the second 95-96. Despite the similarity in the style, they are different style bumpers. You may also notice design details such as the splitter extending onto fog lights as well as the grill you've mentioned. The grill is not interchangeable and is specific to the year 95-96. Luckily for you, the 95-96 comes with a pair of real fog lights vs. 92-94's cornering lights that many forum members converts.
