Far out thats just silly expensive. As Rob says, any decent brake place will do em easy, but there is one tiny catch for people who want to keep it all original. As far as I am aware last I looked at it, the modern fittings on the ends of the lines have metric spacings between their flats. Original was imperial. Thread is the same of course. The imperial spanner sizes on the fittings may still be available (apparantly, were a few years back) but not available (I found) in any sort of hurry. As you dont want any part of the brake line open for long on a rebuild, asking the suppliers and sourcing the parts is worth the planning if you want to be fussy enough to keep the car non metric. (If your exsisting brake connectors are in good condition, and the flats aren't rounded off, your local brake shop may consider using your exsisting connectors).
