Yeah its possible, its just not popular to do. My T, which I havent touched in I dont know how long, had the windshield cut down to four inches and ive just got an indian blanket on the floor as a seat. Theres a lot more legroom without having a back to the seat. Of course im the weirdo here, since ive got a ford 200 six banger and 3spd ala a 65 mustang instead of the standard 350/350.
