Here are some pictures of my bracket, but these are after I modified it , in the front of the bracket by the windshield there are two spacers attached to the bracket. I cut 1 inch off both of the spacers to bring the whole unit up tight to the headliner. After I did that I cut the box off and made a larger one to fit a double din radio, but still using the same Kubota mount.
I did this because I wanted my DVD / Backup monitor to stick down as little as possible.
So now my dvd player only hangs down 1 inch more in the front then the factory radio mount did.
All these pictures show the mount 1 inch tighter to the headliner in the front.
I don't know why Kubota wanted the front to hang down so much, the back of the mount is right up tight to the headliner why not make the front that way.
Also it tips the radio so you can see it better from the seat in the cab.
But try your mount the way it comes first, then check these pictures and the angle of the radio before cutting yours. see which way you like it better.
See what I mean about the Kubota mount , you would have a hard time making one with this nice of a fit from scratch. Unless your 4shorts, he wouldn't have any problem at all making that mount. He is the best I've seen at fabricating.
