I just wanted to post one more idea. I'm wrapping up on my 68 currently. I had my original hinges and I bought repops. I had repops all painted and on vehicle. The test fit of the hood was not going as planned and nothing would fit?? It could have been the repop fenders etc, but that's a different story. Anyway, the hood still would not fit properly. I ended up putting my old hinges back on w/new springs. Still didn't fit to my liking. The only fix was to auger holes out to fender? With the hood being up in the back like yours is, I would auger the rear hole out on the top to make the hood go down in the back. Let me know how it turns out.
