GavZR

I have a 2005 MG ZR which has a Ford IB5 gearbox, I have recently been toying with the idea of trying to fit a short shifter but I keep hitting brick walls with lack of info. They never made a short shifter for the facelift MG ZR so I was told to look into Fiesta/Puma/Focus short shifters does anyone know if they will fit straight in or if the casing/gear linkages are different? Particularly interested about a Puma short shifter as I know one for sale local to me.

Any help at all is greatly appreciated!!
