Looks like maybe a 67? Just because it doesn't seem to have the hook sticking out on both sides of the latch. I know in 68 the government mandated a safety latch on the hood in case it didn't get closed all the way at least it wouldn't fly open. I have an extra 68 latch but it's bolted into the whole support structure.
Think I have an extra latch around somewhere. It's brand new but I can't remember if it's for a bird or GTO. I'll try and fing it and see. I'll let you know what I come up with.
Looks like this one is the 69 type without the handle. I suppose you could fix one on there and make it work. Brand new $25 plus the cheapest way to ship I can find.
