GM-GMC: GMC 1997 headlights, yellow tinge, plastic lenses

Question
Can you suggest anyplace to get a set of headlights for my 1997 suburban that have glass lens? The original headlights are in there now and lenses are so yellowed that it is really cutting down on headlight illumination. I don't want to replace with another set of plastic ones if possible.
Or suggest best replacements that you know of.
Thanks: Allan

Answer
I am not aware of any aftermarket kit that will convert the plastic lenses that you have to glass lights.  There are kits available to convert to HID or projector style, but they too are plastic lenses.  There are kits out that are made for buffing or polishing your plastic lenses, that would not likely remove the yellow tinge.  
I will check into it a little further and if I find something I will update the post.
Hope this helps.
