Here's what mine looks like. Remember that I am 5'6" tall, about 150#:
From the passenger side. The seat backs run up against the bar. When I take the bar out, I can recline the seats a lot more.
The next two shots show the mounts on top of the rear seat fiberglass
The forward mount is under the seat cushion. With some easy mods, you could move the bar rearward 2" or so to get more seat travel, but that's about it.
This shot shows the width of the bar versus the seats. With my cabriolet-style seats, the seat out edge is actually wider than the roll bar. If you have typically narrow "Speedster" seats, the seat back might fit inside of the roll bar.
My rear seat cushion is anchored but this is the forward mount at the edge of the seat.
Next, is the same as shot #1 but from the Driver's side. I guess my concern would be getting the needed leverage above and behind your head to maneuver yourself out of the seat. It's a very rugged roll bar so I'm not worried about pulling or pushing on it - It's going to stay put - but it's kind of an odd position to get any needed leverage from, but maybe I'm not seeing something that you might.
