Fitted today. Couldnt find M10 spline. Thats not torx, something like VW set of bolts M10 size. Strouts are Stabilus 350N 50cm hole to hole. It works great. 350N seams realy just the right force. 50 cm length of strouts can be 1-2 cm longer. With 50 cm hole to hole is a bit lower ther with arm. Arm puls the hood even higher. Bolts and washer i painted whole with touchup kit, basecoat and clear. Basecoat peals easy, when I tightened up. So need to touch up more a bit. But overall is better when painted. Must put some greese to keep water away of inside bolts holes. Hood bolts needed 2 washers each. Plastic head of struts now are close to those hood metal holders. Bolts are long ones 25mm.
