Am I crazy? This u-shaped piece at the bottom end of my shifter (shown facing up in the picture) comes off, right? I'm swapping shift knob, ad I need to reuse the u-shaped piece on the replacement shift knob - but for the life of me, I can't get it off. I've hit it with penetrating oil and and impact wrench - no dice. Any ideas?

At this point I'd consider just buying a replacement part, but I can't find a part number for the thing. I've got a pretty good-sized project on hold because of this little thing...
