Hmmm, now I'm confused. I went to get photos of the pieces I have and noticed that the part number does not match what you have in the original post.
You asked for: 986.504.119.00
I have: 986.504.129.02
Typically, if there are changes to the part only the last two digits will vary as a new revision is introduced. When the last set of three digit numbers is different, 119 vs 129 in this instance, that would indicate a different part altogether. Using google images however it does appear that the two parts are the same, or at least the same at a glance. I'm wondering if the 119 was used on 97-99, and the 129 on 00-04 and that there are some slight differences that I can't detect because I don't have one of both. Sorry to have gotten your hopes up.
Here are a couple of images of what I have for sale. The bottom one is as close to whole as I've seen a used one. The one on top is rougher, but still usable. I saw that you were using them for track application. Are they mandatory? Let me know if this part number works for you.
