Jeep 4.0 in 69 Barracuda

So the rough measurement (done by myself) shows the back end of the Idler arm being approximately 10.5 inches behind the center point of the Passenger Rear K-Member bolt.

I need any blocking item moved forward 3 inch for the OEM starter to fit. I do believe the Passenger Side lower control arm pivot would just miss the side of the OEM starter. And maybe even the end as well. I do have a option for a gear reduction starter saving me 1.5 inches at the very least. I may have found one that is 2 inches shorter than stock. And its sits high.
