I've seen a few posts similar to this, and in all of them the comments are full of people bagging the idea of putting a roof rack on a sling, to this I say, my car my life. I am currently looking to get the genuine roof racks for an r34 sedan, my car still has the mounts on the roof and as I live in the country and travel a lot it will suit my needs. I've been unable to find any and just want to be pointed in the right direction or even want to buy some. I will attach photos of the mounts. The closest thing I've found is an old Japanese catalogue with the r33 ones listed.
