Interesting problem. I believe you are referring to the Door Latch Control and my LMC catalog doesn't list one for '67 either. It lists one for '68-'71 and a separate one for '72 but not '67. You might consult with one of the vendors that supports the forum and see if they can help you. The vendors who support the forum are usually much more knowledgeable than the staff at places like LMC.
