The answer is quite easy the car needs to be operative under any circumstances.... The Garage where the car is stored cannot be used for spannering. And the space where I can do the repair can only be used temporary. This means once I start the repair I need the according spare part available, means I have to order it in advance. And before I lay underneath the car remove the clutch hose measure the thread put the clutch hose back bleed the clutch i think it's quite easier to ask somebody who may have an idea about the size of the thread.
Anyway I got the info tonight, the braided hose is already in order
