How can I tell if a fender skirt is an original skirt? I have a set that I got with my 55 Bird but I dont know for sure if they are real or after market. No identifying marks or serial numbers on them so I just dont know. So I thought I would ask you guys. I got the car aout 20 years ago. The car and the skirts were blue at that time. But they could have been aftermarket then ? No idea . Thanks in advance.
