Figured I would throw up a few pics of how I did mine... might offer a few different ideas.
For mine I ended cutting the rivet/bolt that connects the arms to the fender mount. I then switched the fender mounts from one side to the other and re-attached. I also created a custom (?) flat stock piece to hold the back edge of the hood down once closed. Also note in the first pic the "stop" that keeps the arms from flipping/moving to far forward. when open my hood does not sit completely vertical - some like it that way, some don't. Again, just some thoughts to add to the mix when using these wonderful hinge setups on our trucks.
