Fiberglass hood and hinges

I have a 6 pack fiberglass hood on my 73 Duster. I tried to use the factory hinges with the springs removed. I could not get it to line up at all. Now I just lift it off when I work on the car. What do/how do you mount a bolt on hood and get it to line up. I am thinking of just pinning a 4 corners, but would much rather have it bolted on.
Any suggestions?
