Yup, no problem! Again if you don't mind spending half a day drilling and setting rivnuts, it can be a pretty good deal and save you $500+ over a new set of 470 sliders. I also personally don't like some of the 470 sliders that wrap around the frame - I think the 5th gen 4Runner sliders with the giant frame plates are a better mounting system. You could probably lift up the rig into the air by the slider with a crane and it would stay attached with 13 bolts per side.
FYI my sliders are
All-Pro/Apex sliders. They were $700 shipped when I bought them from Summit Racing in 2021 but are now $900 shipped. I would assume those RCI sliders have the same length as the All-Pros but you should verify. The Apex sliders were a perfect fit for my GX470 - vertical position and how far front/rear they went.
