Oil Filter Access Panel screw Replacement for 2001 blazer/bravada?
 

Does anyone have the part # or know of a good replacement for the lock screw that is used for the oil filter access panel? My original fell off, I tried using a larger metal screw, but it backed out and was lost. The local scrap yard I use to get parts doesn't have any of these panels with the screw. I am wanting to just find the original part and replace it.
The panel is just swinging open, and I hear it's not a good idea to let it do this since it apparently interferes with proper cooling and can cause the engine to run a little warmer than it should.

Think I found the pin on ebay. We'll see...

Yep, It works!
