Ordered a Clutch Master Cylinder from Moss (also new wheel nuts, and decal set) which was received during the week while I was working away. Looked in the manual to see how to remove the Master cylinder and found that on the later cars (this one), there is a bolt through to the bulkhead accessible from inside, under the dash. Checked on forums and apparently its relatively straight forward although one guy had to glue the bolt into his socket. Anyway, I’ll have a go and see what happens. Need to buy some clutch fluid and will need to learn how to bleed the system once all bits fitted.
