I haven't tried it yet, but I think a person could use a dremel with a cutting blade and cut off the tab on the limiter. Once that is done, if the screw is free moving you should be able to take it out - If it isn't free moving like many of them, you could break it off. Might want to remove a few things to give you more room. I'd also consider using one of those flexible tools that fit on a drill on one end and you can slide a selection of screwdriver bits in the other. If you go slow and possibly have an assistant pull the trigger on the drill it may come out without bruising your knuckles.
