That's NOT a hood pin!!!
The original owner had his battery stolen (no inside hood release), so he took a six-inch-long piece of 1/2"-diameter threaded rod, attached it to the radiator support, drilled a matching hole in the hood, and ran this threaded rod through the hole in the hood; drilled a small hole in the threaded rod and put a lock through the hole. Beautiful... LOL!!! I'm not making this up..
I've been so busy, trying to make this thing get out of its own way, I haven't had time to get that ugly hole fixed... This car's not too big on aesthetics, anyway... :angry7:
One hood pin is not a concept I embrace.... But, I can surely understand your thinking that that's exactly what that was.
