How to Move Shackles in 3"

looking forward to the next installment. I like the clean installation...too bad the factory didn't do that to begin with.
Thanks.
I was thinking that too. Maybe they had a policy about hacking frame rails for the front boxes. But they could've done a nice, neat job.You don't want to see my welding on the front boxes. lol But I'll post the perch install photos and odds and ends as I install the 9".
