Clutch Slave Cylinder - creative wrenching?

[achtungE30]

Several threads cover bleeding but I cant get the top most nut off. I even bent the hard fluid line out of the way upwards, but theres no room to get the open end wrench in there to loosen it.

Everyone on here seems to have replaced there's without problems. What did you do to get to that top most nut.

Help guys! I'm so close to doing replacing it, its not even funny. I got the 2nd nut off w/o issue, its just that top most nut I cant seem to pivot my wrench once gripped.

I guess ill try again brute force with my 1/4 ratchet and socket.

No go with my ratchet/socket, open/closed 13mm wrench and a ratcheting close end wrench, just cant seem to grip.
