Hello All, Are there any differences From the BU lights installed at the Factory in '69,compared to the Service replacements C9ZZ.The Ford over the Counter items? I know the 67 Housing was used, and there were different styles of lenses used.What about the wiring?Did the service parts have the white letters & #'s on them?Which lense is correct for the 69. I've seen short and tall. Thanks JW
