I don't know about what you guys got, but the late 12A we got (series 3 and the very last year of series 2) used the same clutch as series 4/5 N/A. 225mm disk and the pressure plate bolts to raised steps on the flywheel, which prevents putting the wrong plate on. I have successfully used the early 215mm disk on a 225mm flywheel/pressure plate combo in a pinch. (Online seller kept shipping the 215mm setup when my friend ordered 225mm clutches, and we had to get the engine in THAT WEEKEND. I had a 225mm pressure plate to donate to the cause. Worked just fine)

whoever it is that is doing this miss-matching locally to me is adding 12a s3 flywheels to s5 and 12a s1 flywheel ( the uber heavy one ) to s4
--

yes we have the 9.0 lug face for our s3 also

in my recent example , the bloke was given an s4 turbo engine ( with 12a carb adapter ) with a 12a s1 type flywheel and clutch suit the s1 gearbox

and so i supplied the correct OEM flywheel for that combo which is n326
( s4 motor onto M type gearbox )
he can still use his new 215mm disk,,, but needs the 225mm pressure plate as there is significant change in the height profile on the cover to suit the raised lugs
