Jeep 4.0 in 69 Barracuda

Or even move the idler outboard toward the wheel and make a custom drag link and shorter tie rod on that side? Also just spit balling..

There is no good movement of the idler shaft. As it needs to be moved Up/Down to get out of the way of the starter. Moving down would be the easiest, which would put it in danger of impact under the car.
