I helped a fellow mudder install OME springs and shackles this weekend. I noticed the shackle mounts were almost and inch skinnier than the OME shackles. The bushing sticking out prob 3/8 of and inch on either side. I'm a 60 guy and not to familiar with 40 series. They looked oem but I don't know. Are OEM shackle mounts this thin on a 40? Is this going to be a problem with the springs moving laterally? The fixed pin hangers fit the OME right.
