You need to turn the battery on it's side on the clutch line side.
The only thing that you can do to make it easier is to put the clutch on a banjo fitting with a -3 Aeroquip line and that doesn't give you much more room.
Push the cables out of the box to get the battery out.
All I can say is TG for the Optima. Without that someone would be syphoning out the battery fluid to keep it from spilling out in the process.
