Those have been discussed in the main rock slider thread. Overall seems good but from what I can gather from reading what other thought, those need more bolts attaching to the tub.
Just heads up, check the shipping cost. I went to price them out and they were nearly $400 to me which brings me up to the price of other sliders that usually have free shipping
FYI, I just updated and re-ranked the Rock Sliders/Rocker Guard guide thread.
Honestly, if the Savvy's are unavailable and prices for the others that still need modification are so high, and you really need some, it's time to fab your own. I'm thinking about doing a set for my sons 04' Sport just as a project to see how it goes.
