New Brake Lines Brass to Brass?

Rebuilding my 7 1/4" rear end in my 65 Cuda. New seals, new bearings, wheel cylinders, New leaf springs from Espo, Bilstein shocks, new brake lines and T valve....Here is the question....
Pre bent lines have a longer sleeve with a regular metal fitting and also a shorter sleeved brass fitting. (see Pic) The brake lines are roughly pre bent. Everything went together great except I am wondering if I put the wrong end in the valve and wheel cylinder on one side? Brass to brass? I'd rather not go backwards unless I need to.
