You could also try something like this.
When I had to use a similar set-up to change struts on my VW Jetta, I bought a 22 mm, 6-point, 1/2'drive, deep socket, ground wrench-flats on the topsection of the socket, so I could hold it with an adjustable wrench.
I then inserted the required 6 mm allen bit socket, & 1/4' drive short extension, right up through the 22 mm socket.
This way I could hold the strutrod from turning, while being able to undo the strut nut itself.
Have I got you confused yet ?
