I haven't been in a 140, but the club I belong to owns a 67 Arrow and
the leg room in the rear is virtually non-existent, especially if the
front seaters have legs longer than 20". After owning a Skylane, the
Arrow is terribly cramped, especially in the rear. It really is
suitable only for kids.

There was a "stretch" somewhere along the line. I know my 1977 turbo Arrow
III has it. Back seats are "ok" (none of them are going to be great).
Don't have my data books here to know exactly when the extra 18" or so were
put in.
