Here's how I have removed a single hood hinge (remove cowl first). Use a 2x4 to prop up the front of the hood on that side. Then place a 1x4 vertically in the little shelf that is at the top edge of the firewall. This will prevent the rear edge of the hood from sliding backwards. Set another 1x4 horizontally with the end hooked into the opening where the wiper linkage resides. This provides a platform to hold up the rear edge of the hood. You can then completely remove the hood hinge. Sorry, I don't have a photo that shows this arrangement. I only have the photo below that shows the front of the hood propped up.
