The GOOD news: These sliders are great.
The BAD news: These sliders ship with zero installation instructions, just a link to a video that is out-of-date to how they are manufactured now.
More GOOD news: The sliders are simpler to install than the video shows.
Mine shipped with 11 hex-head machine screws per side. (no spares, so be gentle with the threads). They line up with 11 threaded holes in your Tacoma's frame.
I suggest making sure each one of these holes is in good shape before you're trying to muscle a 70lb chunk of metal up to them. I ran one of the screws into each hole (with some goop on it) to clear out any road grime and undercoating spray. If they don't go easily, I'd run a tap through them first. (M10 x 1. 25).
The tolerances on this engineering marvel are pretty tight. If something is 0. 25" off, you would need to enlarge a hole. You will NOT be able to stretch steel. But mine went together fine. Just go slow and careful.
They look great. I'm happy with the purchase. A little over 7 weeks to get them. No valid installation instructions, but easier than I was predicting.
