Hi guys.
My whole family is really tall, so is my boyfriend (6'4'')
I know that they sell "ultra low rails" out there but I dont think they can be used on the stock seats right? I hope I'm wrong but if I'm not, what are the most comfortable (have kind of a bad back) reclining seats that can be "super-low" mounted. Right now my boyfriend (and I a bit) kind of has to slouch and slump in the car to be at the right level. Even for me if I sit with my back tight against the chair my head touches the roof. I guess I didnt notice it when I bought the car cuz I was so excited I just sat in it anyway I had to.
But on long trips it's kind of a problem. I know this is fixable and I know you can help or at least point me in the right direction.

Thanks a lot,
bye

Or how much do you think it would cost to fabricate some seat brackets. I only really need a few inches.
