Now assemble the various pieces onto the sliders (this is slider assembly prior to the sliders going on the truck). Install the non-slip sections on the top, and the mounting arms at the front and back. Just follow Slee's instructions, it's straightforward. It's helpful to use a swivel socket and socket extension to get in some of the tight areas around the mounting arms. The hardware for the mounting arms should remain loose, you'll tighten them up later once the sliders are on the truck.

Next, you hand-thread the top main mounting bolts onto the LC frame. Keep them as loose as possible, while still having enough threads engaged to support the weight of the sliders. The sliders will slide onto these loose bolts and hang from it while you install all the other hardware. Don't forget the lock washers on these first set of mounting bolts, I missed that part in the instructions, and had to go back and add them after the fact once I realized my mistake. The Slee instructions are a little confusing at this point because you're constantly flipping back and forth between the main set of the instructions (which are for an LX) and the instructions in the appendix that are slightly different for the LC install. The hardware here is different for the LC than for the LX, so keep that in mind.
It's also going to be a bit tedious bending and winding all the stick-nuts to the appropriate places inside the frame for the bolts to mate with (these are carrying the bulk of the structural integrity, not the rivnuts).
Sorry, I missed getting a picture of just the loose hardware before mounting the sliders.
Now lift and slide the sliders onto those loosely-installed top bolts, keeping the washers on the outside of the slider mounting plate. The slider will just hang in place once you have it on there. It is too awkward trying to do this by yourself, trying to lift the slider, while trying to see and align with the loosely-installed bolts. I found it worked well to have my son lift the back end of the slider, then I laid on the ground and lifted the front end of the slider above me. That way I could see everything very well and get the slider mounting slots up and over the frame bolts.
Here's what it looks like with the slider hanging from the loose hardware. You can see the stick-end of one of the stick-nuts poking out from the rectangular hole to the right.

You're almost done!
Loosely install all remaining bolts and nuts (except for the cross-member supports that aren't installed yet).
Then start tightening the main bolts (those that connect the two massive central support arms to the frames). Do this slowly, and measure the gap between the top of the slider and the body. You want a minimum of 3/8" (per the instructions). I used a jack underneath the support arm (use a rubber pad to avoid scratching) to raise it to achieve the correct gap. This is another time that you'll appreciate the design effort that went into the sliders. There's a convenient slot in the bottom of the main support arms where a swivel socket + extension fits perfectly.
As you tighten these main bolts, make sure slider alignment up/down and left/right is correct, per Slee's instructions. Pretty much all the brackets have long slots where the bolts install that allow both vertical and lateral adjustment opportunities. After the main bolts, tighten the front and back bracket hardware.

The easiest way to measure the gap is to place a 3/8" allen wrench in the gap and adjust until the allen wrench is almost touching the body.
