I ran into the same issue when I installed mine. I uninstalled the shock and moved the ring to where it should be and reinstalled it. I am not sure how you would get an allen wrench back there even if you loosen the three bolts on top, but if you are able to loosen it I think using the fox wrench with lube like Huck says should work fine. I found using some coil compressors made the job much easier though.
I also made the mistake of driving around without remembering to tighten one of the pinch bolts while testing ride height. This ultimately made the preload ring become misaligned and impossible to turn. @FordraptorHero could this be what is causing your problem? I had to uninstall the shock, fix (realign) the preload ring and reinstall it (talk about a harsh lesson learned).
