After the all thread hole was made I measured out to the license plate holes. I put these holes a bit more to the edge of the aluminum angle. Use your license plate for the measurement.
I bolted the all-thread to the aluminum with a nylon bolt on the out side and a normal bolt on the inside, this will make the license plate flex a bit over the nylon bolt. run one normal and one nylon bolt about ½ the way down the all-thread for later use.
I then bolted the plate to the frame with the flange bolts. Then with the first set of flange bolts as spacers bolt to the aluminum angle.
Now go to the car and spin assembly in to the tow mount.
I kept the license plate a bit away from the car so as to act as a bit of a bumper. (it worked good once and saved the front of my car from a rock that just messed up my license plate)
You don’t want a spinning license plate up front so use two nuts.
When you get to where you want to be, tightening the first nut up to the tow mount, then tighten the nylon nut on to it.
