cabinet drawer corner brackets to hold fascia front plate on to drawer

I have a bunch of kitchen cabinet drawers that have two pegs that fit into the cabinet fascia piece. Needless to say, these detach all the time so I end up with the cabinet face in my hand. I am looking for some corner braces that will hold the sides and bottom piece of the cabinet to the fascia piece. I have attached an example of one of the braces that is on one drawer and I need these for all my other drawers. The front of the drawer is wood. The sides are metal. The base is like a laminated piece of particle board. The third picture shows what the pegs that hold the fascia piece to the sides.
