Another method to line up pins , which I used on my Bronco.
Set pin location and fasten...dab a bit of paint/nail varnish etc on pin tops...
....close hood , and presto...self marking inside hood.
Then drill from underside ......
that sounds a whole lot easier.
you could probably even replace "paint/nail varnish" with grease or something similar since it should rub off to mark the spot and you can easily clean it off the pins once you're done.
