could you possibly send me a couple clear photos of what was done on yours?I had the same issue with a MC front diff skid on my last Jeep. MC told me the same reason they told you. My shop was able to make their skid work, but it did require re-drilling one of the mounting holes in the MC skid and using a few spacer washers. That problem has been around for at least three years. I don't see why they haven't corrected for it yet. On this Jeep I used Next Venture diff skids, which I thought were designed better and fit with no problems.
my shop is going to tackle it next Thursday and spoke about flat stock being added to make up the gap from where it is supposed to fit a fastener throguh..... I hear them say there is supposed to be something drilled but they did not tell me where
Just looked from their photos one of the tabs just hangs out in the clear with nothing behind it.
