Nope, this clutch disk is for twin-plate clutches. I don't know about the compatibility of RAM clutch plates with the MG single plate clutch with steel flywheel. There really is only one way to find out I'm afraid...
How confident are you that the clutch is slipping because of a worn friction plate? Some other potential issues to consider:
- Tampered with clutch master slave setting (original clutch handle installed?) causing build up of hydraulic pressure
- Partial misinstallation of the new clutch, causing the plate to not see enough of the "push" from the diafragm spring plate
- Broken or worn fingers on the diafragm spring plate (very normal on passenger cars! Especially Italian ones, don't ask me how I know...)
To be honest, because of the price and unavailability, I would really want to open her up first, before making the decision whether to source a new friction plate, put new material on this one, or change over to dual plate clutch.
