Didn't get it finished but got a good chunk of it done, new pics on my blog and in the garage here. Also updated pics of what the front looks like now.
Somehow the angle on the Kammback changed to 17 degrees, too late to change it now so I'm hoping it will be OK. The roof directly in front of the hatch is 10 degrees already so it should allow the air to stay attached at the steeper angle I'm hoping, but we'll see. Also the rear tires are smaller than the fronts and due for replacement anytime, the new tires will likely be the same as the fronts so that will decrease the angle some.
