Good luck. It's very difficult finding new, regular sized/styled Coleco cart shells, unfortunately. This is probably due to some assholes counterfeiting homebrews a couple years back, so I doubt CollectorVision will come off any. You might get lucky and score some regular, black ones somewhere, but as far as any colored or translucent shells , forget it. I just dealt with this recently myself.. I simply wanted to rehouse my ultimate SD cart in a translucent shell and had a helluva time tracking a couple down. Pkk's shells wouldn't work for my particular project but they might work for whatever you're trying to do. Good luck!
