Tahnks again tango 936. I got the nut loose at the bottom end. Just in case others may have the same task: I could not get a good contact between the nut and the socket. I shortened the socket by grinding the rounded edge down till it was a right angle edge between the plane of the teeth and the plane of the socket end. This gave me the contact I needed, so the nut would not roll out of the socket. The nut broke loose very easily. On to the next step.
Thanks again.
