OMG wurlycorner, if you could measure that I would be thrilled, thank you. The cover plate is 216mm is the measurement directly across the plate that has been taken off of my car. The clutch I bought which was supposed to be right for the car had a cover plate of 215mm and we can't get it to fit at all. I know it sounds like not a lot but it's a huge difference. I have been forced to send my original clutch cover plate to TechniClutch and they are going to try and match it but website feedback on them is making me very nervous indeed and I am trying to keep my hopes in check

I really want to get the car back up and running as I want to do a gumball rally in it this year
Thanks again for your help. Any help and advice given is always gratefully received
