Vs wagon donut gas tank

[1997_vs]

Hey Guys,
Bought a wreck of a vs wagon so i could get the gas tank out of it and put my car on gas. But i'm having some issues getting the tank out. We've undone all bolts on the surrounding brackets that we could see (4 at the front and 4 at the back), all hoses are off but it seems to be somehow held back in the middle is there a hidden bolt or anything i can't see?
Thanks
Mitch

could of been welded to the body somehow when it was installed cos brackets are secure but i would take
any secuity measures so that it dont come off.. dangerous stuff
