72 Dart raised body lines

The light hood hinge springs that you are looking for would be from an old Dodge Daytona, not sure of the Plymouth Arrow's are the same. The orange spring is the light one. I am sure that if you ever need a pair, placing a want ad will produce a pair. Replacing the spring isn't as hard as it looks. Finding a hood like you want? They pull molds from stock hoods. If you buy a fiberglass hood and are familiar with doing glass work, it can be done. Easier than making 2 molds to graft mounts for the chrome inserts on my '69 Dart, they don't make that hood in fiberglass. Think that your hood looks fine.
Good luck
