Landho: If you take a look at the the carpeted cargo area there are a numer of black plastic "Grommets" or "Tabs" that have a surrounding plastic washer... The center part of the "Grommet" is just a ridged "Push Pin" that fits inside the surrounding plastic holder "Washer"... There is a tool that most mechaics have that looks like a two pronged fork that you can work under the "Grommet" and slowly pull back to remove it... Be sure the tool is under the tab of the "Grommet" not the surrounding housing... Pop each grommet carefully and the surrounding holder wil remain with the carpeted cargo area piece... then the peices will just slide out so you can get to the area you are working on...

Hope this helps...
