SL-20 and ST-20 Tool Compatibility

Our shop currently has a 2001 SL-20 with a 10 station bolt on turret. We have a brand new ST-20 with a 12 station bolt on turret on order. I am trying to figure out if we can keep any of our current coolant blocks and bolt on tool holders or if the mounting bolt pattern on the 12 station turret is different than the older 10 station. I'm afraid that it is different and nothing I have now will work on the new machine. The tooling package that comes with the machine leaves a lot to be desired compared to what I currently have in the SL-20, and to buy the missing stuff I need new from Haas is absurdly high priced for what it is.
