I am in the process of pushing out the bushings and replacing the worn suspension hanger pins. All of the holes are in good shape and simply needs new bushings. What I am wondering about is how to address the wear marks on the inside sides of the shackles and the hangers that are riveted to the frame? Looks like round wear grooves. See attached pictures. Do I simply dress smooth and add a shim? Truck is a 1954 GMC 1 Ton.

Thanks all
