roll dows the windows and look at the top edge of the glass,you can see if its two pieces sandwiched together with celluloid in between or one smooth piece of glass
you may have a small "bug" in the lower passenger side of the windshield for safety windshield glass
look on the firewall under the data plate,there may be a makers tag there indicating who made your car
if not, let me know as there are a few other places where you can determine who made the body,i will send photos of where to look
