Thank you for the pictures Steve. I will try to have some drawings by tonight. I've never scanned anything to this computer before, so I might have to do the first rendition in Solidworks.
The plan in my head is to have the Kammback bolt to the trunk, yet still extend to the sides of the vehicle, hopefully mounting flush with the roof and C-pillars. In order for the trunk to open, the Kammback will have to be able to rotate upward at some location, and perhaps it can be as easy as using an aluminum door hinge from the hardware store.
Get back to you soon.
