Removal of stock exhaust manifolds question

[blink32]

Not a problem with bolts or anything. Its about removing the manifolds themselves. The heat sheilds that surround the plugs and plug wires prevent me from slipping the mani's up or down. The sheilds are circled below in red and I just don't see a way to remove them. I'm missing a bolt or something somewhere. Anyone got any ideas? By the way its the passenger side giving me the problems now. I haven't tried the drivers as it looks like there's more room for lateral movement.
