Brake line help

[Todersauce]

The issue isn’t so much with the lines from the frame to the axle I bought new superlift SS braided lines for the frame to the caliper in the front. My main issue is the size of the line. The old line is ¼” and the new SS line is 3/16”. I went down and got 2 adapters ¼” to 3/16” and it will work on the passenger side because it is a simple connection. But the drivers side has a “banjo bolt” (much like the bolt that conects the flex brake line to the caliper) and when I screw that bolt into the adapter there is a gap where the fluid can leak out. I have looked at a set from a 72 I think this might work but I think my best bet is to is just by new line and accessories and cuss and cry and make it work.
