Ed, if your camera has a Graflok back -- look here
http://graflex.org/speed-graphic/features.html#GraflokBack for pictures and explanations -- then the procedure for attaching a lens whose rear cell won't pass through the lens throat is:
remove focusing panel
unscrew rear cell from the lens
'
attach front cell and shutter (on a lens board) to the camera's front standard
wiggle the lens' rear cell through the camera's gate and screw it back into the rear of the shutter. This can be fiddly.
replace focusing panel
If your camera has a spring back, this procedure isn't practical. In that case, two solutions if you want to keep the Fujinon. Replace the back. Graflok backs to fit Speeds can be found. Replace the camera with one that has a Graflok.
You haven't said what size your camera is. Is it 4x5?
