If I'm understanding correctly - you've got the lock nut off but can't get the second nut loose because the shock shaft is turning?

You just need to get a bite on the top of the shaft with a pair of vise grips to hold the hsaft stationary while you loosen the nut. Some PB Blaster will help too. There is actually a special socket for the top of the shock shaft, I usually use a 1/4 open end, or similar sized metric, unless the nut has been tightened to much. That is when I graduate to vise grips.
