My hard clutch line blew and the local autoparts stores don't carry the metric, I'm guessing, fittings. Anyone know the size?

 

Someone has surely replaced these lines?!?

 

I have an idea, run a rubber line from the slave to the master. Every piece less the fitting that goes into the master will be replaced. Nothing left to fail. Any downsides? I was thinking maybe having more rubber that it will flex more, but I'm unsure.
