Oil filter adapter trouble

I have Doug's on my Barracuda with a 5.9.

I took off cylinder #2 slip tube out from the top and was able to get it. But like @moparker said, it's a *****. The challenge is getting the gasket on the right place. I think I used Gaskicinch to hold it in place.

Yup, then there's tightening it up with the wrench as @Keith Mopar noted.

Place a bright light under to help you see. It CAN be done.

After installing and removing the driver's side header, I believe I can reach just about anywhere, lol.
