I am 6'3" 287#. The original seats were unacceptable as it prevented any form of driving. I removed the seats and had some ("cushions") made that look exactly like the seat but rest on the floor and the bulkhead. I went down 6" and back 7". My head is now well below the top of the windsheild and I feel like I'm in the car rather than sitting on it.
