brake lines

[clive f]

anyone know what the thread sizes are on the copper brake lines?
I need to replace the front copper lines and would be nice and easy if someone knows what the threads are in the male fittings screwed to the plate in the drivers side inner wing, and at the other end where the female screws onto the adaptor which connects to the flexi pipes going to each caliper.

I think they are UNF Cliff, I did consider changing to metric when I did my brakes, as they were all OK I left them, but would certainly consider converting to metric if they needed refreshing?
