You could always look for a factory slantback. There were only 39 or so made, but there is one for sale from time to time.
I haven't ever removed the rear window, so I don't know how hard that is. I suspect that it wouldn't be too bad.
Just for Buck, we will make a special Elocker version with lots of buttons.
One button to actuate the locker, one to override the Low Lock Only function, one to override the MPH limitation, and one to turn on the massage unit in the seat bottom. Of course a full array of lights and a lovely female computer voice will annunciate the activation of each function.
