Best I can come up with based on what I currently have in notes, Ford documents and pictures I offer the following
1 - The buildsheets show different drivelines being installed during the production year
C7ZW-G (from car dated Sept 66)
C7ZW-A (from cars dated Nov 66, May 67)
C7ZW-H (from cars dated Jan 67, April 67, July 67)
2- Below is an example from a scheduled March 67 built car matching your car as far as options
Hope this helps in some way
