[Willie in Houston]

I am 6 ft 3 and not exactly small. I find that most earlier Model T's have more room than the later ones. Ford lowered everthing in 1926 including the seat. I think the most uncomfortable T I have ever driven is a 1926/7 touring. My knees jam against the steering wheel. The seat is not adjustable and would take a lot of work including sheet metal extension and seat material extension. Almost anything can be done.
Good luck
