1998 vs 2003 Boxster bodyparts

[steved0x]

The 2003-2004 rear bumper cover is different than the earlier models to match the differences in the rear spoiler on those models which has more of a "tail" hanging back toward the rear of the car for styling purposes.

I don't know if this would work, but maybe you can get the spoiler too and retrofit it to go along with your new bumper?

Woody has a note and picture near the end of this post about the different brackets from 97-02 and 03-04:

Is the "latch" that you are referring to what is also called the "clamshell"


Here's a chart that shows colors, model year, and paint codes. It looks like there are a couple black colors.
