You're going to need a partial legectomy!

Model A's are tight for anybody over 5' 9 or 10" depending on leg length. You can play little games with sinking the seat back under the tulip panel, but that will only gain you a couple inches or so. You might be able to tolerate it for short jaunts by frequently moving your butt and legs around, but it's a quite a bit of playin' around.
