Brake line hard end, making new flares

[C1J1Miller at aol.com]

Any recommendations on renewing the ends on a hard brake line (at the point where the flex. rubber lines connect).  Rounded off the nut a bit, and want to put on a new one.

What's the specs for the line, 10mm x 1.0 male, and is it ISO or double flare?

I'm going to try the local NAPA, or a foreign parts place, to see if they sell new nuts and a flaring kit.
