NO "L" on the ends and looking at the helix of the thread portion that I can see appears pretty clear they are unfortunately RH threaded. I was attempting to turn the correct direction. So the truck is currently not movable as I pulled the master and slave cylinders and removed the brake cylinders from the passenger side for rebuild (the whole reason this topic came up). Doing this outside at another property I have where I park the truck. I don't have a way to get 1200 ft/lb on her. (Even if I borrowed the tool from a buddy, I assume a portable pancake compressor will not feed the need of a big impact wrench).
I'm off tomorrow and will try some heat with cheater bar and if no luck maybe get a service truck call out to break em free. Any other suggestions? Still seems odd though, the passenger side was tough but I did it by hand (and leg) using the 18" breaker bar and did not have to use the 4' cheater pipe.
