'67-'69 Camaro Hood Hinges

[binky3]

How to identify original '67-'69 Camaro Hood Hinges? Thickness of metal? Were there any "markings" stamped on the head of the rivets or anywhere else on each hinge? Please help. Thanks

Original factory rivets at the pivot points typically have a "K" inside three concentric circles on the rivet heads, and the peened back side of the rivet looks like a large phillips-head screw impression.
