Somewhat cracked gauged cluster plastic cover

Regardless if it's a trim cover or the clear bezel, you're best bet is to find a used one in a salvage yard. Your car is old enough that the parts are likely no longer available through the dealer, and if they were, they'd likely be quite expensive. There should be plenty of these around to pick from.

Look for a yard where you can pull your own parts. That way you can take the replacement cluster apart first to see if there's anything else you might damage on your old one. If you're anywhere between Ohio to southern Georgia, and now to the west too, do a search for "Pull-A-Part" to see if there's a yard near you. You pay your two bucks, throw your toolbox into one of their wheelbarrows, and you can spend all day there. You can also do a search to see which yards have your year and model, but they can't tell you colors, options, and which parts are damaged or already gone. I've been to 16 of their yards, and all were very clean and well-organized. Parts are inexpensive, and the employees and other customers have always been very friendly. There are many other similar yards popping up around the country, but none are as clean or organized.
