Mustang Bill

Hey guys I need some help. A couple of years ago I disasembled my 69 Mach I. I am know in the last stages of the build. I am ready to install the windshield, the problem is I have the two little metal supports that supports the glass but do not know were they screw down. I filled a lot of holes and must have filled the holes for this support. If someone could tell me the location of these supports I would "mucho gracioas"
