well....I think you might be a bit on your own with this one then! I guess...I've never heard of a classic with a prop rod. I'm assuming your not putting on springs because they're too stiff for the glass??
^ me too, the top of my prop rod sits in the pass side hood pin hole thru the support and rests on the underside of the hood itself (2 layers on my glass hood, support and hood itself). The horn wires make a nice holder for the rod on the driver side when stowing the rod. sorry no pics, Im at work.
Another option (once you remove the hinge springs) is to take a small length of light gauge chain or a cable and place it where the spring used to hook on the hinge. At the rear, use an "S" hook or one of the threaded repair links to keep the chain attached to the hinge.
Or you could always make your own hood prob system using some gas struts like on hatch backs. You can easily figure out the correct shock in the length you desire, just figure out the mounting distance, stroke, and lbs it needs to lift.
