I have never installed sliders before, but am pretty handy. 6 bolts per side w/ washer and lock washer. I used the styrofoam packing chocks (see photo) to support each end while installing the first couple bolts.
Use a somewhat shallow 5/8” socket and keep a 3” or 4” extension handy—- a couple bolts are close enough to the bracket to interfere with ratchet action.
