I had to retrofit this, as it was going onto a Rhino Rack aftermarket system on my 2012 Honda CRV.Since I had NO rails (front to back of car) to clamp onto. Reading the previous reviews (& comments) was VERY helpful before & during assembly.Lots of knowledge there.For the price, a very good basket. Lay out the parts, test fit them, before you screw them together.Make sure you have all the hardware, 2 of my M6*10 had NO head slots, had to replace those.Paying this forward w review.
