Need screws for Inspiron 2200 Laptop

I recently purchased a damaged Inspiron 220o laptop from a friend. The screen was damaged and in the process of removing the old screen to replace it, I misplaced some of the screws. I  looked on the site (dell.com} for a replacement screw set but was unable to find one. I imagine if I gave them a call they would help me out, but since I didnt buy it directly,  Im not sure if thats the best route to take.  Im wondering if anyone has any experience with this issue and resolving it. Thanks.
