Hi, Brassneck69.
I've attached a couple of photos. I snapped them with my handheld computer so the quality isn't the greatest. (As you can tell, we need to vacuum. But, that's the car dealership's problem now.

)
On a left-hand drive, the flip-up table is attached to the passanger seat. You could attach it to the passenger seat on yours but that will put the sliding extension toward the front instead of toward the rear like it's supposed to be.
Best I can tell, it's just attached, near the floor, to the seat using a a couple or three bolts or large rivets.
We don't have a handbrake. We have a pedal that sits along the outer edge of the vehicle.
