I went to Home Depot and got a length of aluminum angle, I believe 1/2 x 3/4. I heated it up with a propant torch to remove the temper and make it soft. It then bends like butter and is easy to form, a slight tap with a dead blow hammer will make it fit perfectly. I drilled and tapped the aluminum and glass and used 6/32 stainless buttonheads to finish it.
