The hard line from the brake m/c's is 3/16" s.s. with -3AN fittings, which is the same as the rest of the brake line plumbing. Since I didn't want to make a mistake bending the stainless tubing, I used some inexpensive steel brake tubing to first plan out and bend into shape. Once I was satisfied with the routing and dimensions, I duplicated the line in stainless. The lines were routed down under the m/c's and away from the pedals over to the bulkhead fittings.
First two photos are tube bending in progress, and the last photo is the finished result with the two brake hard lines and the clutch flex line.
