Anti Sway Bar

Ok so I decided on the Addco 751 Anti Sway Bar I called and had them email the installation instructions. They seem very clear just one question Is the front of the Bar mounted to K-Member? If so do I drill the hole myself? What if my K-Member is bent?

Excerpt:
"Assemble angle brackets (the one with two 3/8" holes) plates
and bar brackets over the neoprene bushing as shown. By
adjusting the angle bracket align so that the hole in the
horizontal portion matches existing inboard hole in front lip of
frame cross-member. It is pictured with larger leg of angle
horizontal. On older models with the C-section frame cross-
member, drill a hole in the bottom side to make the angle
bracket bolt."
