If I remember correctly, my BAL kit did come with bolts and washers and nuts, not self tapping screws. The hardest part of the entire installation was drilling through the I-beam. Not hard, just time consuming. Use a center punch first. It's also best done with a super sharp bit, on slower speeds. And constantly removing the bit to reoil the tip. It's important to use cutting oil or even 3 in 1 oil. Slow and easy with a little pressure for best results.
