The shifter is not a big issue. Between aftermarket units or modifying a Ford unit, the controls can be done. We have done a 65-66 Mustang shifter to control an AOD unit (understand that the "drive" dot now becomes "second" and the second gear dot is drive) it can be done.
Add an in tank cooler to the radiator and use the "
oil cooler" in the nose as the aux. trans cooler and you are golden.
