Dell Latitude D520 key fell off, need part

Hi all ya smart notebook folks.

Well I read the hardware sticky and did a search but didn't find the answer to this one. My Dell Latitude D520 has a key that fell off, it's actually the letter "B" and I have the keycap but not all three of the little white pieces that sit underneath it. So what I need is one of those three tiny white pieces that holds the keycap onto the rubber button. Anyone know of a good parts supplier.
Thanks folks. -Glennski

 

Well gee I fixed it myself in the meantime, but thought I'd be a good forum citizen and send the solution
The link at

gave me the courage to try fixing it myself. That's when I realized that there are only two parts under each key, not three, so I knew I already had the part. I decided to pry off the "windows" key since I very rarely use it, and I actually switched the under-pieces with the "b" key. Then I managed to put the screwed up pieces back together under the windows key. Voila! back in business

Hope this helps others on this board who have similar problem
