I installed these loose many months ago but I didn't tighten them down because I needed to touch up the frame in that area. These are the front upper shock mounts. I used CPP CPPUSH-K. I nickel plated everything in the kit. I ended up using stainless AN washers against the frame and a locking nut for a cleaner look. The through hole in the frame had some rough spots that had been painted over. I smoothed out the hole and touched up the paint. Then, I installed the shock stud with nickel anti-seize at CPP's recommended 154lb/ft.
