Thanks Kevin for the comments. I think you are right but I have one question.
How does the large wing nut holds the tire, plate and the hook in place? I tried to add the large wing nut on top of the backside of the smaller hook but that seems wrong in a way. You can't twist the wing-nut at the end to torque it!!!
I was fortunate to find the same model of hook as my friend Johans car had so now that one is glass beaded and painted the correct gray color. Actually I bought that one from Don (65 dartman)
Any ides how to hold it all in place?
