My 49 had 3 of those "T" blocks, one at the master cyl to main line junction, one on the frame at the right front wheel and the last one at the rear where the soft line to the axle goes.
I cleaned all of them up and reused them. I also ordered the prebent hard line kit and mine fit perfectly, which surprised me.
Had to chase down several small leaks but once I had all the connections good and tight and the shoes properly adjusted the brakes pumped up as well as Hucks will
10k miles later it's still stopping and holding it's fluid
Good luck
Dave
