I took the top mount off last night, got most of it off, but the bottom rubber bit is stuck in there, seems to be spinning around as if the captive nut is spinning, although it was one of them only times i used the lidl borescope for something i put it in and could see the threadded part of the mount isnt spinning when i turn it:

It is this part which is loose and just spinning, is there any way to get it?

Thats a picture from the borescope showing the threadded part below the mount:
