AC Mounting bolt/header

[phlegm]

I have a strange one, wondering if anyone has delt with it. Ever since I went to a new set of headers, I cant get my AC compressor to line up on the bottom bolt. its off by a lot, like a half inch.

Anyone know if those nuts on there used to move? I am sure the one at the block is seized, but not certain about the one at the compressor side. I may try to pull it off and put it in a vice to see if I can get it to move, or go to the parts store and make one of my own with some red lock-tite and patience (of which I have neither... lol). Pic has it circled from LMC, but I cant find it in their calculator.
