Is there a hood support rod for a 67 Dodge Dart?

I think you lost a spring. Mine is strong and I'm always afraid of bending the hood when I close it.

When open does the hood have a slight twist to it? The low side would be the side I would be looking at first.

The hinges are most easily accessable with the fender off, second with the dust shield at the rear of the front inner fender off and least through the open door if at all.
The springs are not the best. The hood will stay up but a little wind will push it shut. I don’t want to take off the fenders to change out the hood springs but I guess that might be my only option.
