Heat & Bend... if repositioning on the splines doesn't work.
The shifter can be repositioned because of the splines.
If this becomes exhausted and you still cannot find a favorable location, heat the round lever part with a torch and when red it will easily bend into the desired position.
If you are very careful, it can be done in place as long as the flame is small so it won't effect the interior, but is best done outside the vehicle with gradual bends each with a trial fit. Obviously the knob needs removing for the torch method.
Hope this helps.
