Hood Lifting At Driver Corner - Hinge Issue? 1970 Dart Swinger 340

The hinge mechanism is quite simple, the arm is attached to a pivot, and has a clock spring that provides the lift, really nothing there that needs a lot of lubrication. Where the bolts attach to the hood, there is a threaded bar that is caged inside the hood and is able to move some to allow for adjustment. The area around the attachment point can become weak and stress cracked, allowing it to migrate up under the pressure of the spring.
