351W plenum removal

I’m trying to get my upper plenum off on my 1996 351w efi. We took out what I believe is all the bolts but can’t get the plenum to come off. The front half lifts up but the back is stuck down and can’t see what’s holding it down. Does anyone have an idea what is could be? I can feel a bolt with my hand but I’m not sure if it’s a plenum bolt. Is there one in the back under the fuel return line? And if so how do u get it out

The stock upper intake has only six bolts. One on each corner and two straddling the middle. The middle one under the intake runners is a torx socket headed bolt. Other than a support bracket from the exhaust manifold up to the plenum, clearly visible, there should be nothing else.
