Is there a product you can use to make scratches on the silver trim (near the shifter, on a 6MT) less visible? Or, is there a dealer who sells a replacement of this piece?

Also, I need some other parts:
1) 2x gold philips screws which hold the radio in place
2) 2x white clips holding down the plastic piece (middle portion) right under the analog clock
3) 1x clock shroud cover (grey interior), since the clips seem to have gotten flimsy when I removed the shroud

Anyone know where I can get these parts?
