I bolted the yaesu 857 faceplate bracket to this printed mount and it worked great. I've also add a file that has the standard 1" ram ball in case you opt to mount it with a ram mount system.
Update March 2025: Updated file with a center hole to mount the FT891 directly to the bracket.
The author remixed this model.
I used the original concepts to understand how to connect to the truck. I added my own mounting plate to support the radio faceplate bracket.
Update March 2025: I got a FT891 so the added a center hole to mount the new radio.
