Default Opti spark removal problems, help!!

Im in the process of removing my Opti spark. Every thing is loose but I cant get the opti out! Looks like I have to remove the ballancer! Which poses another problem! The ballancer is VERY close to the fwd cross member. Do I need to lift the eng to get the ballancer off? How high does it have to go ? Doesnt look like it will go high enough to gain access to the ballancer.HELP!

loosen the balancer bolts just slightly. rotate the engine if you need to get the bolts at the top to loosen it. when they're loose start the engine for about 2-4 seconds. the vibration will loosen the damper. pull the bolts out and the damper will fall right off.
