"knobs are free" and their method of attachment to the shift lever is also free, as long as said shift lever is unmodified other than the allowed bend (I'm presuming that with the "free" allowance one could use racer's tape or gorilla glue to attach the shifter if one was so inclined )....

But I'm having difficulty figuring out where the ITC states that the knob may be attached to the floor or transmission tunnel, other than via the lever.

The trick setup on this Mustang is a better, more precise way of accomplishing exactly what the allowed bend to the shift lever was meant to accomplish - put the business end of the shifter in a more easily manipulated position for the driver while maintaining the factory part, as opposed to allowing an aftermarket part and the resulting spillage of the contents of pandora's box....

Not only does this shifter not fir the wording of the rule, it has defiled and murdered the spirit of the rule...

just my opinion, of course.
