A body hood torsion rods help

I did the job myself today, thank you so much for your help. The torsion rods needed to be switched from the left side to the right, the previous owner installed them opposite and backwards. In other words "A" backwards. I did see one more problem while I was doing this, the nut holding the hood hinge to the body on the passenger side is missing. It would probably take me a long time to guess which size bolt and thread pitch to find. Does anyone have one? This did cause me a problem while doing the job, the hinge popped off the stud and scared the doo out of me. I managed to guide it back on.
