These work great and they mounted with all factory holes so no drilling at all. Only downside is the block bed lights but if you open them the lights work well.
Box looks and works great. Only issue is installation on 2001 Toyota Tacoma. Box sits on top of bedliner with grooves at wheel well. Not even when sitting on top of sides. Had to engineer"about 1/2 gap on each sides and purchase longer J hooks.
I've been looking for this product for a long time . Everyone that sees it , talk about it being so great . 5 star all the way . Thanks
