Hello, I just finished my install and figured I would share how it turned out. Ford's Boxlink system is compatible with E-Tracks accessories. I used the Handetrack threaded mounts to mount my antenna bracket in the bed of the truck and the results have been great so far! Check out my images below and if you have any questions on how to make it let me know and I'll give you some more detail. I can also make one for you if you are interested. I did 3d Print the bracket between the tube steel and the boxlink plate. I also printed a cup holder mount for my face plate and MFJ speaker combo. I can post images of that if there is interest. There are so many different ways these threaded Handetrack brackets can be used to mount an antenna this is just what I came up with.
