      GM B body rear axle brake line diameter?

      Working on a rear disc conversion and decided to fabricate new brake lines for the rear - I just don't like the extra bends in there.



      Does anyone know the stock steel line size?

      Factory rear axle lines are 3/16"...depending on the year "B-body", the stock fittings would have been either 3/8-24 inverted flare or M10x1 bubble flare.

      Thanks! Should have pointed out it's the 69 model year.
