Well I make a kit very similar to tht Wild Rides but mine have a extar plate that ties it to the frame on both sides and they are made from Stainless so they will not rust.
If you already have the Wild Rides kit in I would suggest, tap all the seams back together and make sure they are square again and FULLY WELD all thr factory seams and I welded the top plates to the floor board as well (The ones under the rear seat)
If your boxes are really trashed and non repairable South Side Machine makes a replacement adjustable torque box, but I have never delt with this so I do not know if it works.
I damaged my boxes very bad since I run the SSM which tend to be hard on the boxes, after welding the seams and adding the re-enforcement kit I have never had a single problem. I also welded plate across the bottom so it boxes the arm in a little. You just need to notch it out so that the arm still has room to travel. Wolfe sells similar plates for $25.00.
