Found these the other day. N-fab doesnt provide sliders (rock rails) for anything but Jeeps but I couldnt imagine they are too much different than a lot of other sliders out there. You think they could work on some 3rd Gen 4Runner sliders, minimal modification?

These look pretty cool!

 

it says N Fab has rock rails available for Toyota on the link you posted. And that the steps fit FJ cruiser rock rails.

its a neat idea though cool find!

 

hmm.. well they don't currently have them up for order. You would probably have to call them to see if they provided rock wells for other vehicles other than what they have on their site. I don't think they provide any products for 4Runners at all though.
