You’ll need a tape measure / rule, hole saw based on the size of the tie down you use and a drill motor. I installed the tie downs far enough apart to fit ammo cans for the JEEP cans project.
Measure between the edge of the fender and the rail. You can center or make the mark a little closer to the fender. You can always grind to fit so don’t worry too much about getting this exact.
Drill the pilot hole and score the cutout spot to check your work. I went with lining up the bottom of the tie down with the top of the fender flare.
Drill out your hole – there is a considerable amount of open space in there if you wanted to fill it with dampening material. If you’re going to use these to hold heavy weight you may want to add steel reinforcements inside the cutout area. I use them to hold down grills / coolers / chairs / lumber and other materials occasionally. If you plan on using these to hang a hammock you may want to consider using steel reinforcements.
Make the same cut whatever distance you want your tie downs to be from each other. I centered them on my JEEP deck project. I used a tap to thread the metal for attachment and as always painted the cut edges and sealed it up with silicone. Paint them to match if you want.
