Ok, so I guess I get the gold star today.
Rather than use a big pair of Channelock pliers, this tool compresses the clamps that secure the front sway bar to the lower trailing arms. Once

Good guess's guys, now it's your turn to show us that weird old VW tool that showed up missing at the VW dealer,
and you bought at the swap meet. wink wink nod nod
