Sorry, I have just about every other spare headlight part other than that bolt and bushing. I believe what your looking for can be found at zip-corvette.com. Do a search for P/N's HDL-125 Front link pivot bolt and HDL-126 Front link pivot bolt bushing. They are $6.50 and $2.50 respectively, may be slightly higher because I'm looking at an older catalog.
Interesting, never seen one of these missing. Rusted and snapped off a few times but never just missing. With that bolt removed you should be able to raise the lid by hand without raising the rest of the mechanism. Hope that's what your looking for, Good Luck !!
