Note: the good looking brackets aren't the ones i made. They're ones other guys made. I suck at fab. But you'll get the idea
draw it out
carboard template (so you can get it to scale)
Fold it like you'd bend the metal
grab some angle aluminum
Cut and bend it like your cardboard.
hopefully your results are better than mine. but you get the idea
you can mount the cluster flat on it, or get the N brackets.
If you're doing N triples, you need a couple brackets off the N, and should probably get the back cover. Parts #10,12,8 in this diagram
