Brake Line and Subframe connectors

I haven’t finished mine yet, but my current plan is To add a bulkhead fitting through the factory frame rail just behind torque box. I drilled holes through the crossmember right next to the rocker panel, and then I cut down (up) to those holes, took out the piece, Laid the tubing in, then put the piece back and welded it in. I drilled a 5/8 hole on the outside of the original frame rail large enough to pass the tubing through, now I intend to put a bulkhead fitting on the internal side of the frame rail.
My big question is: should I put a shepherds hook bend in the tubing and use a straight bulkhead fitting, or just use a 90° fitting.
