I need to remove my ams exhaust manifold in order to get to a leaking line. I'm having trouble accessing the nut on the top row, second from the passenger side. I can't fit any tools in there b/c the manifold is so close to motor. I"m sure im just missing the right tools but I'm not sure what they are. Any help appreciated! For reference, this is the manfiold. The bolt is on the top side, right in between the first and second runners.
