So…..just for grins, let’s say that slotted nut is screwed in.

find yourself a screwdriver the full width of the nut. Use a hacksaw, file, dremel cutting wheel, or side grinder to remove enough of the center of the blade to clear the pin.

Might not work, but you’re only out a screwdriver.

I was on the same wave length, was thinking a wide paint scraper or similiar tool...
