A complete line from Goodridge in the exact size you need should be less than $80. You would need two, 35 degree banjo bolt fittings, one box of crush washers and the desired line length.
From this place:
2 Chrome banjo bolts are $17
1 box 10 mm crush washers $4
The brake line should be about $40 (around 40" or so is my guess).
You can get info on how to measure for the line at the Goodrige site (read this first, I didn't.....)
