I used Thule drip rail mounts...they use a square tube that goes through the feet. my Con-ferr is actually mounted to the cross braces of the rack though. You would have to weld to your rack to use just the mounting feet.
those are a good example, RTownsend.... I am going to use that as a base for makin my own.... Gotta finish this rack tonight, need to paint it tonight.
Lemme know if ya need a pic of the feet, if you are building your own rack the mounting would be real easy, and you could buy the thule feet and be done.
