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 an 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.
Ok, so on my setup, I’ve got about 11” from the center of the rear k-member bolt to to the back side of the rear support bar. The support bar I have is curved toward the rear about 2”, so if you’d do a straight across support (which I could actually do on my car as well) you’d have about 9” from the rear k-member bolt to the rear of the support bar.

Here’s a picture showing how my rear support curves.
