Ok so that worked. The story so far. The motor is out and as the photo shows we found a broken clutch lever and also broken holder into which the lever slots. Amazing that I drove a 200km rally with it in this condition.
What I have learnt is that these parts are difficult to obtain. Three Morgan dealers have so far failed to come up with them and Burtons does not have this type. Luckily I'm a member of TM and Arwyn saw my difficulty and generously sent his spare lever. Through Morgan friends here I have tracked down a second-hand thrust bearing and holder. I am not happy about putting second-hand parts in but they are in good condition and the car can't sit in the workshop much longer.
So on Monday the parts will be fitted and all being well the Mog will come home Monday afternoon. I will update. Cheers for now and thanks again Arwyn.
