Well, I finally made time to take a pic of the new front shackle(s) position. Mount points moved back approx. 3/4˝.
Also, when the springs were taken off, there were signs of wear in several spots across the #2 leaf, so the shop added pads to each end.
Jeep rides "softer" now and has less bump steer symptoms. For now, this will do for me. incidentally, I finally scored a decent set of stock YJ springs, for an SOA conversion in the future. I don't know if this will require moving the mount points back to "home", but I'm okay with that. SOA isn't in immediate future plans.
