As soon as mine ships from jegs I'll be doing the same exact project. How did you end up deciding where to drill the holes in the k member? I know mine doesn't have it also a 64.I figured what I do was the same as I did on the rear it's just kind of eyeball it and get it as centered as possible.
Yeah, I just mocked up the sway bar, then used some yellow paint with a q-tip to mark the spots to drill on the frame. When did you order the sway bar? Mine took 4 months to get to my house.
