hi ben
i have the exact same shocks...unfortunately i am missing 2 of the adjusters...and they cant be got anywhere....i would strongley advise you adjust them to what you want and then remove them for safew keeping...even leave on in place and transfer it across if you need to adjust them... they lift up and there is a spring under the little flat head piece..total 3 pieces in them....
also i finally have managed to get them pics of your car from over here together..so hopefully get all on disk soon and sent of to you...
