Tony there is some bushings in the rear cab mount shackle. I had expected they would have rotted away. But when I pulled off the shackle mount (leaving a healthy shim between the cab and frame) I was surprized to find the bushings seemed okay. One thing does lead to another. I now realize that until the rear springs are examined and repaired, rebushed, pins and bolts, won't really know just how it will really sit.
Adding to the difficulty, I was not able to park it on a slab to have a level frame of reference. So I guess the next step will be to tear into those springs.... :rolleyes:
