mine's a 98 civic... won't the junk yard pose the same problem I'm having now?? my headlight clear cover is dirty, yellowish and nasty, when I have my headlights on I can't even tell that they work!!

I tried taking it apart to clean it and tried everything but the improvement is negligible...

so wouldn't the ones at the junkyard be dirty and nasty too? I'd rather just buy a replacement clear plastic cover if possible to do so without actually replacing the entire assembly.
