I did my torsion bars last night too.
I fabricated a tool from a flat ironbar ( 5 x 20 mm ) and drilled 7 mm holes for both of the adjustable end of the torsion bar end. One of the holes is right at the end of the bar and cut open from the end. Then it was pretty simple installing the torsion bars, though with some strain holding the bar.
