Can you upload an image of what you are seeing? I would try using a 1/4 inch drive extension and a 10mm universal socket. Here is a diagram I don't see why you would nee to remove the harmonic balancer? Check out the images (below). Let us know how it goes

You may want to check if loosening an engine mount and lifting the engine with a crossbar would help. That will generally get you an inch or two of extra room.
