1993 buick century 3.3l v6 spark plug/mount

I am trying to change my spark plugs but the mount for the engine to the car is holding the front spark plugs in a case between the mount and the engine. I can get all the bolts off for the mount except for one. The bolt I cannot get off is in between two fuel injectors. What I'm asking is if there's another way to get the casing holding the spark plug wires out or if there isn't how can I get the bolt off. I tried uploading a picture but it keeps saying the entity is too large. Any help will be appreciated.

I can't remember if this year has engine dog bone mounts on the radiator support....if they do, put car in neutral(apply ebrake), and rotate the engine forward and you can wedge a block of wood between firewall and engine component(alt?), to create more working room in the back of the engine....
