Update...My hood droops closed on its own....again!
The new Jegs hood springs worked at first to keep my hood open but now the hood closes on its own just as it did with my original hood springs. For now, I re-installed the SS hood spring to keep the hood open. Even with the SS hood springs, the hood tend to droop down about 4 - 5 inches.
I need to focus on the hinges because they must have too much wear in the rivet pivot joints. I plan to prop open the hood, remove the spring, and unbolt the hinge from the hood (one hinge at a time) to get a closer look for loose rivet joints.
I assume my hinges are warn out and will consult with Willie Wilson at Hood Hinge Repair. Based on reviews they do good work, but I prefer they not paint the hinges so that I can have them re-plated in gray phosphate as original.
I will keep you posted!
