Does anyone know what size the hard line fitting is on the brake lines of an 89 n/a? I think they are 3/16" metric thread... I just wanted to make sure... Is this also the size of the port on the brake calipers?

Thank you.

 

In case you are still wondering, it's 10mm X 1.5 pitch for the flare nuts and the caliper fittings on a single caliper system.
