Guy's if you have a vice they are easy to make.
Just get some metal strips in the correct ht and cut them a little long for the brackets.
If you cant find some in the correct ht than get a sheet and scribe it with a sharp object or dremel than bend and snap, unless you have a saw of some kind than use that.
next use some stiff material like wood or plastic as jig plates in the open vice. (taped in place)
put the metal in the vice and close all the way.
open vice and remove piece.
next mark off the edges, holes and "V" shape.
drill all the holes including a large one for the bottom of the "V".
next use a saw or dremel to cut off the access on the edges and the "V".
round over the corners with files and sand paper and your done.
I made 4 sets for the DZC armor.
