have you checked with euro-salvage yards? i know that in the pittsburgh area, there are shops that deal only with Saabs, and they have lots of wrecked cars sitting around with parts waiting to be bought.
The college i attend has a 1987 900 turbo, they are about to junk it. I might be able to get you the parts you ask for. (provided they fit your year, i know very little of saabs). As far as the headlights the lens of one of them has a rust stain on them and both of them are yellowed. Let me know if you want me to get the parts.
