I will try to get photos up soon, but it's really easy to check the lower mount point of the shock to see what I mean. You'll see a nut on the inboard and outboard side of the shock and mount location. This usually means it's either 2 pieces (not in this case) or a stud. The stud has 2 diameters, the first is about 3/4 inch OD and the next is about 1/2 OD. The 1/2 inch OD size is the threaded portion of the stud. The larger part fits into the mount hole at the rear of the spindle. The low mount of the shock is cast into the back of the spindle. I just found an insert, in this case the inner race of a bearing which fit snugly into the spindle hole. Then I used an SAE bolt (the metric bolts were more expensive) 1/2 inch fine thread with washers to center the shock to the top mount opening.
FWIW, the Santa Fe isn't mine, it's my sister-in-laws. I have a 08 Honda Pilot (my wife's car) and a turbo Miata which is piloted by me @ HPDE NASA events.
