Pawlowski, I presume you are talking about the "Nikkormat FT2", am I correct?

Neither of those optional screens provided for the "Nikon F" series cameras (F/F2/F3/F4) doesn't fit with the Nikkormats, I'm afraid. With the Nikkormat series cameras, you have only two choices, which is either "A (split)" or "J (micro)" type screen, and those are not the same optional screens available for the "Nikon F" series cameras.
