Frank,
My interest in removable side windows stems from the desire to be able to drive "with the window down". It just happened that something I was looking at may be the answer to the problem being discussed. Certainly, it's simpler than divorcing the wife which, according to my friends who have tried it, doesn't leave you with enough for the car anyway!
Removing the door is certainly a possibility. My doors have been on and off the car dozens of times during my build. One drawback with it is that, as in my case, there may be a significant wiring loom to be unplugged as well. Possible, but messy. My concern is more to do with the fact that, one day, you're going to drop the door.
If I can get the Frontera clips, etc to work, it will do me nicely. Maybe the answer here is to install Lamborghini style hinges. Although they're a bit kitsch, access to steer and push the car is there with NO removal of components. I gather the kits are a bit expensive too. There will be a certain amount of derision from the "classic" GT40 people but hey, we're big people, we can live with that.
On that note, I'll leave you.
Very Best Regards,
Lance
