I need to order some parts for the fuel system on a '67 coupe I just picked up. Until now, I didn't know that there's an early and late version of the fuel line. The date code on the data plate is 05M. Does that mean the car was built in December 1966? If so, that would mean it uses the early fuel line, since Ford apparently switched to the later style sometime in February 1967.
I just wanted to be sure I'm decoding the date code correctly, as I want to get the right parts the first time!
