To guide this back on topic, I did some shopping today
I got the aluminum flat bar, rivets, coroplast, hinges and adhesive foam tape for between the kamm frame and the car, a total of $68.
I like Aerohead's (Phil right?) idea of hinging it at the back. It still is a possibility, but so far I am still leaning towards hinging it at the front, that way I can open the trunk without the weight of the kamm on top of it, which I think should make it a little easier. Then at the rear of it, I am leaning towards using a hood pin style system from the trunk lid to the kamm frame. It will centre the kamm, keep it secured at the back and still allow very quick and easy access.
As far as the actual build goes, I am going to add the details and pictures to my existing thread, 2000 neon aero mods. I can't link to it right now, but I will do that shortly.
Thank you all for your help. I have to get to work soon and work every day, so it may be a few days before I can start building, but its coming soon!
