I purchased a hood off ebay and of course one of these were missing.
I shook the hood hoping it was stuck in side somewhere but for sure it was not.
They were supposed to be in captive like boss similar to the door strikers.
ones
I ended up having to make my own out of 1/4" flat steel then drilled them and tapped them. sliced the hood and slid them in.
I am pretty sure with in the last year some one from the SACC (solid axle corvette club) had done a how to article on replacing them in the "On Solid Ground" magazine. I will check past issue today.
Have you shook the hood. Blown compressed air into it to see if its still in there Shook the hood again?
The biggest problem with making them is trying to get them to stay in place when bolting up the hood hinge. I had to kinda put it in place then drill and tap my new boss for a small 1/4" pan head screw I used to hold it in place until I could get the hood bolts in. Once I got my hood bolt in I removed my pan head screw and the boss was being held by the hood bolts ,then I adjusted my hood Then redrilled and tapped the boss again to hold the boss in that position so I could remove the hood in the future with having to worry about the boss falling out of place.
This was a real pain to do
Good luck
