[s-cars] rear brake lines

[Kirby Smith]

Teddy:

This sounds more like a problem with properly specifying the lines than
a problem with Paragon lines per se.  As all my sets are for OEM brakes,
I can't comment on getting Paragon to make up something special.  But if
I were doing so I would probably send a drawing.

Sorry, but I forgot if you were re-lining your stock brakes or adapting
non-OEM brakes.  In the latter case, you might consider buying brake
line material from Paragon.
