Here is what I'm trying to do. I picked up a used pair of high steer knuckles made by rocky road, and they have been drilled til fit 5/8 heim joints, so I want to reuse my stock drag link and HD tie rod and just thread in some 5/8 heim joints and misalignment spacers where the drag link meets the knuckle, and on the driverside of the tie rod where it meets the knuckle.

Eventually I'll make my own drag link, but I'm pressed for time as I'm only a week away from a wheeling trip. Any help is appreciated, I need to get these joints ordered quick!
