Hey, i'm doing my 5spd swap, and i'm having a REALLY HARD time removing the hydraulic lines from the clutch master cylinder. At first I wasn't sure it was the right size wrench, because on the cylinder, it says 5/8. i ended up using a 10mm open-ended wrench, but that stripped the nut a bit. what can I do to get the line off of the master cylinder? This is the only thing that's stopping me from going on to bigger things, like dropping the tranny.

I could use a vice grip, but that would defnitely be a risk in stripping the nut.
Any other solutions for people who have done this, or have just replaced their master cylinders?

thanks,

There are special flare nut wreches that need to be used. Got mine at Napa

 

what size needs to be used? I really need to know so I can go pick it up at autozone.
