Brake line help

[1964Barracuda]

I'm looking for the correct brake line for driver's side rear. I purchased a complete brake line set years ago and am just now installing them. Being installed on a 1964 Barracuda. 741 rear end. I don't know what year the axle is or what it originally came from. It's possible that the axle Tee block is wrong but I believe that I just have the wrong brake line. What year/model brake line should I be looking for? Any suggestions for a source?
Thanks, Ken

This block looks like it would fit that line configuration if the barrel nut were removed. You are welcome to it for shipping.

How bout if you roll the block over, other side up ?
