Horseman 45fa and nikkor 90mm sw

[cam]

Hi, I have recently come across a Nikkor 90mm f4.5, and have discovered that the rear lens element will not fit through the front standard of my Horseman 45fa. I am able to use the lens by removing the rear element and putting it on from inside the bellows, however this is not ideal. Just wondering if anyone knows of a resolution to this problem?
Cheers

Van Camper is right.

Here is the complete list of suitable lenses for the FA, in case you find something other than a Nikkor.
