Trying to pull the gas tank on my 68 galaxie, i have loosened the 4 bolts around the neck and removed them as well as loosening the 2 bolts for the straps under the tank. There is a flange connected to the body by 8 bolts and the neck is soldered to the tank. What else do I need to do to get it to drop?

(also marco input is useful here)

I am making youtube vids of my progress, I will post them all when I get it ready for inspection but I'm a little stuck at the moment cause I don't want to disconnect more than I need to or hurt anything.
