Need Help finding a part. Mounting bracket for 1967 Dodge Dart Convertible top cylinder pilot bracket.

That missing stud is similar to the studs that the hood hinges hang on. I was missing one (for the hood hinge) on my convertible. I used a pin bought from Home Depot, cut it off and welded it in place. I may or may not have an extra or two, but right now with three cars (all convertibles) apart I don't know what's extra.
