Goodridge also do them for the S12. The rears replace both smaller lines with one single "long" line, however, they need to be clipped in place on the subframe to stop them getting trapped.
The fronts are direct replacements but when the car is jacked up and it's on full lock they are a little on the tight side, some MOT testers will complain about this but they can usually be talked around.
They do them in Zinc plated or Stainless steal and they are around £70 for the full set.
I got my set from
