These are not repop hinges, they are the orig. hinges that came with the 67 vert. I also have a set that came on a donor car, 67 400 coupe and they had springs that had 28 coils also and they don't hold the hood up either. Could someone tell me if their springs have 28 coils and are all FB springs the same. I really don't want to put pins in every time I open up the hood. Thanks Eldon
