Just got off the phone with tti and they said they do not offer a header that will work with the 727 colum shifter, only floor shift. I really want to keep it looking original in the cab...
there are always options. I would go with their early A or shorty header, and one of these shifter cable kits before I would cut fenders or add floor shift.
I would go floor shift if you are planning to go manual valve body
