What is this access plug?

[Mark04]

This access plug is missing from my car (2004 4.6 SOHC). I need help finding a part number for it. It is on the driver's side on the engine and it allows access to the flywheel/flexplate bolts. I have spent hours looking at www.fordparts.com without luck.
Pictures are what it looks like.

are you in a hurry for it? I dont have the numbers but if you can wait a week or so i can grab one for you out of my store, just whenever the next one rolls through.

No hurry, God knows how long I've been driving without it. Thanks!
