What exactly do I need for 67 hood to fit?

[MandarinSixSeven]

I know it has been asked about a zillion times before, but I did a search and came up with nothing.

What do I need to make a 67 hood fit? My truck is a 67 GMC, but for some reason (I'm assuming accident?) the previous owner has swapped to a newer hood (69-72). Now it looks like I have one 68 front fender and one 69, which is really annoying, but I don't even know if fenders effect the hood. To me it looks like the only thing really blocking the 67 hood from closing is the top of the grill, the little chrome piece, but I almost know that's not all it will be...anyway, instead of all my useless blabbing, why don't I let some of you experts help me out

Thanks
