K member blind nuts

boy I pulled a stupid move. I bought a used V8 k for my swap. I didn’t check the blind nuts. Had it sandblasted and painted it today. After it turned out nice.... I see that two of the blind nuts are gone. Damnit. The one will be easy. But I’m looking for easy solutions that might be out there for the one way up in the corner. I could possibly fish it up there and maybe get a wrench on it. Maybe. Wish I’d have caught that before all this prep and paint. Thanks for any ideas.
