1967 Dart GTS Parts Book Info

What is the date the book was printed at the bottom? My early 67 parts book does not have those pages. I would be interested in copies of them if you can scan them!

The Picture pages (23-182 184) says Jan 68, supersedes Jan 67. The Part Number pages (23-183 185) says Jan 68, supersedes May 67.

Ok so these are later additions to the parts books and they updated with the 383 emblems. But they omitted the GTS emblems references.
