So, I know the Jags That Run make rear axle set back plates. I never really noticed that until somebody else posted it. And now it bugs me. So, rather than lower the back of the truck another 3/8" and pay $22 plus shipping, I just did this.

Original position

Target in site

Axle spring perch with hole drilled 1/2' further forward

Back together

As it sits now

As an added bonus it clears the exhaust when I bottom out now. This took all of about three hours to do, and the wheel in now centered in the wheel well.
