The little nuts that hold on the spacers got stuck today when I was trying to remove them, before I had WD40 I went at it with a brace and slipped and rung it. Charged up the Snap-On impact gun and left it soaking in WD40 for an hour the other 3 came off fine then but the one where the brace slipped earlier just kept spinning and rung the head. I was going to hammer on a 16 socket but before I ruin a socket is there a tool to take these rung nuts off. I cant get at it from the side as its sunk down into the spacers.
