I have them on my six days. As I recall the directions weren't very good, you have to remove the bottom outside rubber grommet all together and the rad shrouds have to be stretched a little to line up the lower bolt hole. Also, I think I had to modify the plastic louvers or swap them from one side to the other so they would clear the lower crossbar on the cages. These are very solid cages though, and have done a great job protecting the rads so far.
