Got some garage time in between other projects this weekend…  Started out welding the angle brackets (there is a square top plate with a hole drilled in it):

Then welded the angle brackets to some 2×2 square tubing.  Notice each piece can be attached to the car in three different spots.  These are what will attach to the car:
