back focus again!!

My mate has kindly lent me a WO FLT 132 with FF for a trial spin. I am trying to work out if I can fit the Microline 8300 plus filter wheel into the back focus needed by the field flattener.
The diagram is here http://www.williamoptics.com/accesso...ChiptoLens.jpg

As can be seen the optimal distance is 46.45mm which makes it ideal for DSLRs plus T ring.
The back focus of the microline is 24.96mm. THe SX filterwheel is 25mm in width. Hence 49.96 which puts over the 46.45mm FF spacing required.
Any ideas?
This not including any special connectors/adaptors etc
Thanks for advice folks
Graham
