I received the pictured gizmo below with my used Boxster. I have found 2 images of the exact looking device online, but not in any great detail. Instructions accompanying the device refer to a 911 (996). The instructions refer to "plastic forks" and "S10 plug-in pins". Am I missing some necessary parts? I have it assembled correctly I think. I am just unsure how the long horizontal bar is mounted. And I am assuming the long rectangular holes in the closeup are for the 90 degree red handled hold down levers on the top to attach to the device.


Any help would be appreciated. Thank you!
