Oil filler neck

I have a 2003 GT, does anyone know how/if the oil filler neck can come off the valve cover or how it is attached? Mine is cracked and I wanted to try and replace it without having to get a new valve cover. Any pics of the bottom of the stock valve cover would be helpfull too. Thank you.

On my 02 it comes out, but is a pain. There are some little clips that clip up under the valve cover kinda fits in between. Sorry probably a bad explanation. But whenever I put my JLT intake on, it was hitting the cap and broke a couple of those little clips. I went to the Ford dealer and they told me they did not manufacture that. Pissed me off, so I just put it back on and pu tsome gasket sealer around the bottom, haven't had a problem since. Also cut the oil cap into just a circle the same size as the filler. Hopefully you will have better luck finding it.
