Shadowed this forum for a while looking for fellow enthusiasts for these great automobiles, finally became a member after a while but haven't posted anything yet
likes: getting up on even a cold winter morning and having my 132,000 mile cutlass start within 1/4 second of a turn of the key; it's beautiful stock everything that works perfectly; how I baby it.
dislikes: The HORRIFIC creaking sound coming from under the left rear side of my car; which can be compared to wedging two nailed-together boards apart with a crowbar.
What's causing this? I have some pictures of where I think the problem rests, it seems like this little rubber do-hickey kind of...rotted away...and now this fiberglass looking bar is resting directly on the metal. The possible culprit?

Rubber *thumbs up*

No rubber *thumbs down*
If this is the reason that my car is creaking, what will it cost to fix and can I do it myself? My knowlege goes as far as changing my fluids and changing the brakes
Thanks for reading
