I have a 78 and know that the hood is original. It does not have the ridge. Sadly I was the one to bend the hood back in the mod 90's. This is before I knew to oil the hinges. I'm careful now with it but I've noticed it getting worse. Since I'm planning on stripping the paint and repainting the k5 it is time for a new hood.
Did GM make any other changes to the 79-80 hood to fix the hood bend problem?
Does anyone with a 79-80 have a bent hood?
