I remember making that switch years ago and the old flimsy Cessna cover didn't seem to fit as well. It's weird because the Concorde is shorter than the original Gill. I think because it was sealed battery I didn't worry about the fit and just set the lid on the battery and strapped it down with the original hold down. Eventually I had to replace the lid as it was in really poor shape anyway and bought a lid from Aviation Enterprises that is fiberglass. It fits really well and much better solution. Not cheap but I have had years of use with no regrets. My original box is still in use.
