1995 Lincoln Continental Oil leak

I have a small oil leak coming from the front passenger side of the motor and i can see where its coming from but dont know what gasket to get, its coming from where the ac compressor mounts into something else which mounts to the block. leaking from between the block and what the ac compressor mounts to. What gasket is that and how hard of a job is that? Also does anyone know where i can get an exploded diagram of my motor to see everything? Thanks
