I have a SRC on my 2006 TJ. I liked the relatively inexpensive price and decided to give it a try. Finish is/was ok, with a small wear spot from shipping. Fit is/was 9/10, with the installation being greatly aided by a second set of hands. The plastic knobs are pretty useless and mine cracked or popped off, before I finished the install. I am in the process of making some knurled replacements, with heli coil inserts.
The nut, within the knob stayed secure, just the plastic outer assy failed. They seem to be mainly cosmetic anyway.
I couldn't find a matching basket or ladder assembly that I liked, so I built my own, to fit the rack. I can post pics, if you would like. It is reminiscent of an old school Land Rover.
