I have the 4 piston set up on my car ( original ) The brake lines that come off the bracket that bolts to the caliper bracket are a metal line. they come from the rubber flex hose with the same size fitting but when they go into the caliper they seem different.Should I have 1/2" left and 7/16" right ports or 3/8 left and right. I was told that the assembly line changed them mid way through the year because the employees were putting the wrong lines on the wrong side. does anyone know??:(

I know the ones on my 68 Camaro are two differant sizes, and they were the orginal ones. I was told by the people that rebuilt mine that that was how they came.
