One more item comes to mind for another mod to enable a tall driver to be comfortable in an a Model A roadster or coupe......that is to lengthen the doors. 3" seems to be the most ofter extention length. To do this you have to lengthen the frame 3" in the door area.

Frame mfgs can do the frame work for you.
Don.......or you could go w/a mid 30's car but, even w/the mods the A would probably be cheaper to build & be different.
