All 1967 through 1969 Mustang/Cougar and Fairlane/Torino/Montego/Cylcone models were serviced with the same part, C7OZ-2B091-B.

Yes the same . Marked C7OA-B was assemblyline in 67, C8OA-B was 68 /69 and a general service replacement C9OA-A. They all look the same on the outside with the exception of the engineering number  and they all perform the same and interchange with each other. There can be different rebuild kits depending on the specific valve you are rebuilding.

If your interested in the small details they were also dated - as to when the part was assembled. Happened to have a C7 example handy

They do not - there are differences in the tubing fitting sizes.  Here is what was serviced:
