Struts? I imagine you mean shocks. :-)
They make a double socket contraption just for this situation. It is a smaller deep socket with the oval indent to fit the tip of the shock, and then an outer sleeved socket that fits the actual retaining nut. If you were closer, I'd let you borrow mine. I think Eastwood or Sears sells them?
