This is what I come up with, cut off the old lines, drilled them out to 9/16 and tapped them 3/8 npt. The one side with the restriction I cut off approximately 1 inch because the factory pressed in fitting or line spun when I was trying to get it out, it ended up workin my favor to clear the tb anyway. Also I drilled and tapped the holes that cross feed each rail 9/16 and 3/8 npt and plunged them.
