That back lip sounds big enough to mount to for sure. I like the previous posters idea of a pressure locked/ spring system. How were you planning on making these covers? If you're using fiberglass then it would be able to holdup to the idea. Again going back to under the fender wells.. Perhaps a subframe can be mounted to bolt the final cover to? that lip sounds big enough for a spring to pull down and lock it into place or to mount a back plate to. I have the cover pictured in my head... I'm looking forward to the results.
