Most all of the resto places have them. This picture is from Jack's Auto Parts. By the way, the brackets have a little forward-and-back play so you can further center the pins through the holes. They should be body color, if you've got the paint. Put the pins in the bracket holes, but don't snug them down. Measure for hood hole placement or put a dab of white grease or something on top of the pins, gently put the hood down against them, and then lift the hood and see where the grease marks are on the bottom side of the hood. When you drill through the hood for the main holes, start with a small drill bit, like an 1/8". You can still see if you're centered on the pins and then drill with increasingly larger bits. Dab some paint on the exposed metal of the hole.
