+ 1I didn't order them, because I had no clue what to use them for.
Yesterday I went to the agent to see my car for real and, guess what, I got them anyway... for free...
and suddenly I have to figure out what use them for.
I think I will stick some spare fittings on them for "the looks".
I am sure we will find some real problems that can be solved with help of the mighty rails!
