These are stock Knuckles that I see advertised for more than I offered them for. These are not drilled for anything, they are stock. The steering arm is a stock D44 arm. The stud is one of the six that hold the spindle on. They are pressed on and only cost a couple of bucks. I bought them this way.
I was going to save them for future use. I ran into about $4-5,000 worth of work needed on my truck. I am also going in for surgery in a week or two.
