Spent a few hrs at work and cut out a couple tie downs myself. Like Aussie, I copied the profile of my front HD tie downs for a matched set look. Luckliy the profile was nominal dimensions so it was an easy to copy and program. The mounts on my '17 may be a bit different than what my '15 was. I recall the '15 just using 1 screw and 1 pin, where as my '17 uses 3) 3/8" -16 and 1) 5/16-18 screw. The 5/16 is a shoulder bolt in the bottom hole, with the 3/8's holes used for height adjustment. I 'want' to say they are not an exact fit between yrs??? On mine, the wife uses the top location, so I made the mounts just with 2 holes leaving out the 2nd and 4th hole and will not reuse the shoulder bolt (4th hole location) and instead will use 2) 3/8 bolts. More solid this way too.
These I made from some scrape 3/16" 304 SS, milled out on the CNC. Bending was a PITA! Had to really clamp it solid so it wouldn't roll and distort. The bending is the obstacle if you don't have the right equipement. Our brake proved to be a little lacking. And for just the 1 set, you improvise. LOL Nevermind the swirl marks, and distorted appearance. Those are just from a quick pass over from a scotchbrite pad on die grinder to get a smooth surface. Going to a chrome plater this weekend. $50 min fee for plating.
