Hey guys, does anyone know what size/ thread pitch the fittings for our hard lines are for our brakes?

You might try Mark or Auto Recambi. They sell the nut bot top secret on the size.

Just wanted to update this.
I was sent a link from a friend to the place he got them from.

At least you have the size. The next issue is do you have the bubble flare tool? http://www.youtube.com/watch?v=4fmF9mm3hsM

I think the flare is a metric bubble flare (ISO) not a SAE or DIN. At least that is what I recall when I did the lines on my car a couple years back.
