[RTTY] 75 baud question

[David VE3VID]

I would like to try 75 baud in the BARTG event but am unsure on how to set this up.   Currently using MMTTY with N1MM, set up for FSK done by a Kenwood TS-450.   
What settings need to be able to do 75 baud?   
The TS450 has FSK shift settings of 200 450 and 850hz.  Do I set one of these for 75 baud?   
On MMTTY setup under Decode tab, BaudRate setting - Is this the only adjustment for MMTTY?
