Here's a thought.
Get the install kit for the Cheetah cable to the trans. Install your shifter just like you normally would, just route the cable down the right side of the trans, across and back up to the trans. like the Cheetah does.
With the bracket for the Cheetah, that should be doable. One issue is getting your cable to clamp into the Cheetah bracket.
More than one way to skin a cat.
