Removing standard rear indicators.

Hi,

Quick question.

Trying to remove the standard rear indicators from my SD, 12mm nut on end of indicator, when I get my spanner on it, it turns but doesn't loosen, something is spinning inside the rubber shaft of the indicator, same thing happens on both sides, I cant see anything else to grab hold of that will stop this spinning.

Has anyone got any ideas?

Thanks in anticipation of your help!

Had same problem - sleeve nuts seized onto threaded indicator shaft - only way was to Dremel cut the sleeve nuts off.
