Did the 69 Mach1 come with a sun roof?
The first gen Mustang never came with any form of sunroof from the factory. However, many dealers would install them during purchase for a customer requesting one. Back then the majority of the sunroofs were of the sliding cloth "accordion" style. If it is like that it very well could be from the period. If it is a glass or plastic flip up style it was most likely installed in the '70s or '80s.HTH...Mark
